I’m following the supplied examples and was able to list packages and buy one product. Although the process do not reach the end because of a raised error, but the error is very general, and not clear at all. Also it does not have any error code as it was supposed to according to the docs here (https://docs.revenuecat.com/docs/errors#android-errors).My Code:try { const offerings = await Purchases.getOfferings(); if (offerings.current.lifetime !== null) { const currentOffering = offerings.current.lifetime; const { purchaserInfo, productIdentifier } = await Purchases.purchasePackage(currentOffering); if (typeof purchaserInfo.entitlements.active[ENTITLEMENT_ID] !== 'undefined') { console.log("Purchase Success"); } }} catch (e) { if (!e.userCanc

Hey,I’m using react-native-purchases library and found some issue in Xcode logs. Every time initialise my app is initialised I send identifiers using:useEffect(() => { Purchases.collectDeviceIdentifiers()}, [])RevenueCat is returning error and complaining that IDFV cannot be modified. Am I doing something incorrectly? Below I’m also attaching log. Thank you 

Hey,Currently, I’m experiencing a strange behavior when the user has one google account and logged in on two different devices and also the user has two accounts in my app.When the user is purchasing a subscription on one device this subscription is applied to both accounts of my app.I'm expecting that it should be applied to one of my accounts and the second account shouldn't see this subscription.Can someone help me with it?didn’t find an answer for this issue on the forum =(

I've setup the Facebook and the Stripe integrations for my Android app, but the fb_mobile_purchase i setup as a target event doesn’t get any events. 

I’m continuing the discussion from spectrum here:@ryan your docs don’t make any distinction between iOS and Android when it comes to whether the Facebook SDK should be installed, so I assumed it had to be installed on both platforms. If not, that would be a great thing, as the SDK is huge.

Hi, I have the following questionIn your documentation, under the Subscription Status tab, it clearly states that the subscriptions field is a collection (array) that stores Subscription objects within it. And this response I expect from the REST API. But as far as I noticed, making request to API "subscriptions" is an object that stores fields in itself - so it is not a collection. And this can be seen in the "Rest API endpoints" documentation where in the "Get or Create Subscriber" request the example "subscriptions" is just an object instead of a collection. Could you please clarify this inaccuracy for me? Because when I currently make a request to the API in "sandbox" mode, I also get the subscriptions{...} object instead of the subscriptions[...] array.Thanks in advance

Using RevenueCat for Unity, I am receiving json return values from RC in response to GetOfferings, RestorePurchases, etc. They usually come in the form of a PurchaserInfo object. I can’t find any documentation anywhere on the exact details of what is in this object.Specifically the date values look like this:"originalPurchaseDate":1626733276,"latestPurchaseDate":1626733275EDIT: Ohhh, these Ints are just the values shown by the XCode debugger, in C# the object contains dates in DateTime type. I was looking at the raw json data and wondering what those date numbers stood for. Still trying to find in-depth docs for the C# Type PurchaserInfo, what all is in it and how it behaves.What are these integers and how does one make them into a date? Does any documentation exist detailing the return values from RC calls?Thanks!

Background: In my flutter app it is possible for a user to sign out and another user to sign in without restarting the app.  To support this feature the app calls Purchases.init whenever a user logs in.  If the transition is non-sub to sub this works as expected IE the latter user sees their subscription. But this does not work if transition is sub to non-sub.  In this case RC fails to update to non-sub and the non-sub user appears to have a subscription until they restart the app and the sub is gone.Fix: reset all data when Purchase.init is called.

NSInvalidArgumentException *** -[__NSCFConstantString stringByAppendingString:]: nil argument This class of crashes occurs when the Purchases SDK is unable to find certain keys in NSUserDefaults, usually due to clearing NSUserDefaults. The Purchases SDK uses NSUserDefaults to store information. By default, standardUserDefaults are used, but you can configure a different instance of NSUserDefaults. To do this, set the userDefaults parameter in configure:guard let revenueCatUserDefaults = UserDefaults.init(suiteName: "com.myapp.revenuecat") else { fatalError("can't create user defaults for RevenueCat domain")}Purchases.configure(withAPIKey: <your-api-key-here>, appUserID: <the-app-user-ID>, observerMode: <observer-mode>, userDefaults: r

If you have an active subscription that should unlock an entitlement but it doesn't, make sure that subscription's product is added to the entitlement in your dashboard.

Check out our new and improved walkthrough guide!  If you're still testing in sandbox, it's most likely a configuration issue that's preventing the products from being retrieved from Apple/Google. Your product identifiers are set in RevenueCat, but the actual products that your users purchase can only be retrieved directly from Apple/Google. Because this communication happens between your app and the stores, RevenueCat doesn't have any visibility into the API requests, however there are some common requirements to go through.iOS and AndroidThe product identifier set in RevenueCat matches exactly with the store You're testing on a physical device and not a simulator

Multiple subscriptions? How?Although rare, it's possible for a user to have multiple active subscriptions. On iOS, this could be done by accident if a user has multiple devices using different Apple accounts and purchased on each one. On Android, a user may have tried to upgrade/downgrade a subscription but instead purchased a duplicate. If using RevenueCat to make purchases on Android, you need to specify in the purchasePackage method whether it is an upgrade/downgrade, or else it will be treated like a regular purchase.If neither of the above cases apply, or you see a lot of subscriptions on the same user in RevenueCat, you may have hardcoded an App User ID instead of using a unique identifier for each user. Each subscription is actually associated with a different Apple or Google account, but each one is tied to the same hardcoded App User ID in RevenueCat. In order to separate these users out, you should release an update to your app that clea

If you feel like a subscription or trial should have expired, but you see that it’s still active, then that subscription is likely in a grace period.For example, this user signed up for a 3-day free trial of the 1-month subscription on May 5, 2020 which should have converted on May 08, 2020. However, the dashboard shows the expiration date as May 24, 2020. This is because Apple applied a 16-day grace period due to some billing issue. Apple will continue attempting to bill the user until they successfully do so or reach the end of the 16-day grace period, at which point the trial will no longer be active.  

If you're receiving an error message "Invalid Play Store credentials" when attempting to make a purchase on Android, it's due to the service credentials that you've added to RevenueCat being invalid: https://docs.revenuecat.com/docs/creating-play-service-credentialsBefore you go and generate new credentials, it's important to know that it can take anywhere from 24-48 hours for Google to propagate your service credential access after they're created.There are a few places to check your configuration. You have followed the configuration steps outlined in RevenueCat’s

This error could be due to a few reasons. Try the following troubleshooting steps:Make sure your device/emulator is completely updated. Try running on device. Sometimes the emulator glitches out and it must be restarted. Overall, testing on device is more reliable. Restart your device/emulator. Make sure you're logged in with a Google account. If you're running on an emulator, make sure it has Google Play installed.

Apple will randomly generate billing errors for auto-renewable subscriptions in sandbox. This is expected behavior; it's part of Apple's sandbox environment so that you can test for the billing error case.

Our charts are in UTC, all other dates in the dashboard (such as customer activity) are in your local timezone.

Refunds are issued differently depending if the subscriber purchased through the App Store or the Play Store.  App StoreApple does not allow developers to issue refunds on behalf of users. Users will need to contact Apple customer support directly for a refund. RevenueCat will automatically detect when a refund has been issued by Apple.If a user requests a refund, you can direct them to the Apple support page: https://support.apple.com/en-us/HT204084 Play StoreThere are multiple ways to refund a customer that purchased through the Play Store:(recommended) Active Android subscriptions may be refunded directly through the RevenueCat dashboard. Click on the respective transaction event on the customer page and hit "Refund" in the upper right. 

Did a user reach out to you saying their card was charged after opting out of an auto-renewal? This is possible, and there are a few reasons why it happens:The user cancelled less than 24 hours before the subscription was set to renew. The Apple subscription terms require users to cancel subscriptions at least 24 hours before the next renewal. The user didn't actually opt-out of renewal. Some users will delete the app and expect the subscription to be cancelled. The user somehow has two subscriptions and cancelled only one of them. This is uncommon, but can happen if for example the user has multiple devices using different accounts. The user might have opted back in renewal after opting out.Inspecting the Customer History timeline in RevenueCat can help determine which of these scenarios may have applied. It's important that you can co

How can I change my plan?You can change your plan at any time from your RevenueCat account plan page. ‍See our Fair Billing Policy for more info about upgrading and downgrading plans. Why don't I see all the premium features for my app after I've upgraded?If you've upgraded your account but don't see the premium features (like charts) for your app, ensure that you are the app owner and not a collaborator. Only the app owner can manage billing. If you've upgraded your account as a collaborator by accident, don't worry - you'll only be billed if you're the owner of a live app so you can simply

What is MTR?MTR stands for monthly tracked revenue. It's the amount of revenue tracked by RevenueCat (in USD, and before the platform cut) during a one month billing period. This includes paid subscriptions, renewals, and one-time purchases. Why do you base MTR on pre-platform cut revenue?Our goal is to help you take advantage of Apple's and Google's 1-year cut reductions as well as the benefits of moving subscriptions to less costly platforms like Stripe. This ensures we aren't disincentivized from making that happen. 

It is highly recommended to test on a real device. This is because StoreKit is flaky in iOS simulators - it will randomly fail when fetching products, offerings, etc. Learn more on testing purchases in sandbox in our documentation.

 I've configured an attribution integration but no events are sent?The attribution integrations in RevenueCat (e.g. Appsflyer, Adjust, Branch, Facebook, etc.) require two steps to setup.The network specific attribution data needs to be sent to RevenueCat from within your app. This is done through Subscriber Attributes in the SDK. Refer to the attribution integration guides for the specific network to see which Subscriber Attributes need to be set and how to test this: https://docs.revenuecat.com/docs/attribution The integration needs to be configured in the RevenueCat dashboard for your app.If no events are being sent, you should check that step 1 above is set up properly for your app and the specific attribution network. Integration events will only be sent for users that have these attributes collected.If events are being sent but the
