Using Google Play Billing Library 5.0.0 with purchases_flutter 3.10.0

I use com.android.billingclient:billing:4.0.0 on my application and purchases_flutter 3.10.0 for the revenuecat subscriptions.From May 2022, users can't see the free trial or intro price options. Then, I messaged the GooglePlay and they replied as below:Hello Google Play Developer, Due to a bug in our system, since May 3, 2022, you may be experiencing incorrect or missing subscription information in the results from the Google Play Billing library’s deprecated querySkuDetailsAsync() function. During this time the Google Play Billing library may not have returned information to your apps about free trial and intro price offers for one or more of your subscriptions, even if the user was eligible for these offers. In these cases, users only saw the subscription base plan in the purchase cart, without any free trials or intro prices.Action RequiredWe recommend that you review all of your subscriptions with free trial and intro price offers in the Play Console, and ensure that the correct o

Does the transaction ID ever change for a user/subscription

Can I be confident that the transaction ID sent to the webhook will always be the same for the lifetime of a subscription, or do I need to use the original_transaction_id value?Since I’ll be creating a record in my DB for each new subscription, I want to make sure that I’m not creating duplicate records if a new transaction ID is created for existing subscriptions For example when it renews, or if the same Android user logs in as another user in my app. In the second case, I’d like to be able to reassociate that subscription to the current user.I’m migrating to RevenueCat from an existing system that integrated directly with Apple/Google stores. Both Apple and Google require you to keep a reference to the original (or previous) transaction/token since these will change over the lifetime of the subscription. I’m hoping that RevenueCat takes care of that headache so I can just use a single ID for the lifetime of a subscription.

The item you requested is not available for purchase.

I am currently using Flutter with real android device.  I recently switched to using “Google Subscription Model v2”. I followed RevenueCat instructions over here When I upload my Flutter app to Google play store internal testing, then download the app from play store to my real Android device, I am able to make  subscriptions without any problem.  On the hand, if I run my Flutter app through the command line using “flutter run”, then when I try to make subscription, I get this error: “The item you requested is not available for purchase.”.  Here is a screen shot. I am able to see the subscriptions with no problem on my screen.  I only can’t make purchase.I don’t want to deploy my app to internal testing in play store to test my code as this is so slow.  Is there a better solution. Thanks

Setting Up a perfect Listener

Purchase process in Unity3D SDK

How should purchasing process looks like in Unity3d?  In official docs Unity (revenuecat.com) we see only single function for this purpose:public void BeginPurchase(Purchases.Package package) I think it’s definetly lack of documentation. How should we obtain Purchases.Package object? Create it from new on our own? Get it somehow and store it?

Kotlin 1.4.21 Versipn

"I am working on a large, legacy Android project. I need to integrate RevenueCat into the application, but due to my Kotlin version being 1.4.21, I cannot integrate the latest versions. I tried to upgrade the Kotlin version, but then other libraries started to throw errors. The Hilt library, in particular, caused many issues. I couldn't find a way out. I'm considering downgrading the RevenueCat version, but I couldn't find which version is compatible with my Kotlin version. Could you please help me?"

iOS Swift SDK - Offering Metadata type casting errors

Recently we’ve started integrate the Offering Metadata feature. As this is a beta feature, I believe there is a minor bug in the SDK. Reproduction Steps:Add an integer property into metadata of the offering using RevenueCat dashboard (“myProperty” : 123) Try to read the the integer value using in Swift code: offering?.getMetadataValue(for: "myProperty", default: -1) The value defaults to -1 rather than 123  When I checked the SDK code, I see that the metadata dictionary returned as [“myProperty: “123”]. Then getMetadataValue<T>(for key: String, default: T) -> T function is failing to cast the value to Int even though generic value T is set to Int in above call. It is not a major issue as I can achieve casting in my code but wanted to report it here. I am using:Swift 5Xcode 14.3.1RevenueCat 4.25.0

[React-Native] How to implement addShouldPurchasePromoProductListener?

Hello, I want to be able to process subscriptions that come from App store promos.I found out that this method ‘addShouldPurchasePromoProductListener’ is should be able to process it, but I can’t find an example or doc of how to properly implement it. In my app users have to sign up first before using an app, so what if they click on that promo in the appstore before signing up, what should be the app behavior and method implementation in such case?

RevenueCat does not seem to remember the original userId set for a google account

Here's an overview of my system:My app requests a new user ID from my backend. It uses the obtained ID by passing it to the Purchases.logIn() method.When I get the original user ID from the customer info given from the login callback, it sets the original userid (UID) into its app data. Turns out when I wipe out the app data and repeat the process, the getOriginalid() method returns the same newly regenerated ID used during relogin instead of returning a different id; not considering that the same google account is logged in.I also tried changing the transfer behavior in the Dashboard, but to no avail. I want my app to obtain the original id, even when app data is reset Is there any real way that I can ensure the same user is logging in, even when App data is compromised?

This is the PUT API call:https://api.storekit.itunes.apple.com/inApps/v1/subscriptions/extend/{originalTransactionId}The path parameter includes the originalTransactionId (required, the original transaction identifier of the subscription receiving a renewal date extension). However, I am unable to find the originalTransactionId on Revenue Cat.Here is the Apple documentation: https://developer.apple.com/documentation/appstoreserverapi/extend_a_subscription_renewal_dateHow do I find the originalTransactionId?

Users App Store local region and Locale.current device setting discrepency

Hey,I’m formatting price strings that are returned from RevenueCat (localizedPriceString) in my iOS build but I also need access to the users app store region code to format the currency to and from a floating point number while keeping the correct currency formatting before and after.The number formatter in xcode uses either ‘Locale.current’ (which the user can change in the phone settings leading to possible incorrect formatting) or a manually specified region code. I need the app store region code to ensure the values that I format are returned in the correct currency format.Is there anyway RC can supply this?Cheers,Matt.

Flutter StoreProduct discounts vs introductoryPrice

Hey,I am currently working on implementing Offers and Discounts into my paywall for flutter, and I'd appreciate assistance with a couple of issues I've encountered.Firstly, everything appears to be working as expected for the AppStore. When I inspect the StoreProduct object, I can see that both the introductoryPrice and discounts fields correctly reflect my setup on AppStore Connect. However, the situation is different for Android/GooglePlay. It seems that only the introductoryPrice is being set, and the discounts field remains empty. Can you confirm if my assumption is correct, and Android never populates the discounts field since the PlayStore does not offer that capability?Secondly, I am a bit confused about how to handle purchases of a Package using discounts and intro prices. On iOS, I successfully used the method Purchases.purchaseDiscountedPackage to buy a package using the StoreProductDiscount. However, I'm unsure how to make a purchase at the introductoryPrice.
