I am testing purchases in sandbox. I have purchased a subscription before, and it has expired.

When I go in to purchase again, `Purchases.purchasePackage` prints purchase successful immediately  and returns nothing and stalls.

@tina do you see any reason why this is happening ?

Hi @Programiz , 

Happy to help here! Is this issue still occurring?

If so can you please send over some debug logs? 

You can enable debug logs by following this guide. After they're enabled you'll see logs like this in the console:

[Purchases] - DEBUG: No cached entitlements, fetching
[Purchases] - DEBUG: GET /v1/subscribers/<APP_USER_ID> 200
[Purchases] - DEBUG: Purchaser info updated, sending to delegate

Please ensure the debug logs include the entire app life-cycle, including the messages printed during initialization of the SDK. The more information you include here, the better we'll be able to help.


Let me know if you have any questions!

I have the same issue. For my monthly package, Purchases.purchasePackage() does not open iOS purchase modal in sandbox and instantly returns. Works fine with Annually.

It’s the same piece of code with different products from getOfferings. 

If it failed instead of returning successfully, it would be great we could just handle the failure.


Maybe the reason is why is because after fifth renewal it is opt-out. it is handled by Apple connect.Here it is explained more broadly:

This is still an ongoing issue for us, using RevenueCat SDK 4.0.0 in Unity 2021.3.8. After a few repurchases, it becomes impossible to repurchase that subscription product on iOS.


Those purchases are in sandbox. But it is impossible for us to determine if this is a sandbox-only issue. We never had a similar issue with in our current implementation of Unity IAP, so anwsering this is actually an important issue for us as we are currently trying to assess if the SDK is stable enough to launch with. 


PurchaseProduct conclude with no errors, but the CustomerInfo does not include any active Entitlement or any ActiveSubscription.


Here is a sample of the logs from one of those failed purchase:

We’ve had a few reports of this and it seems to be an issue with StoreKit 1. Upgrading to using an SDK version that allows you to use StoreKit 2 under the hood should help. 

The latest version of our iOS, Flutter, React-Native and Unity SDKs support StoreKit 2, by passing an extra parameter when configuring. 


Could you give it a shot? Let me know if you need instructions for any particular SDK.

If only that worked...sigh.   Added StoreKit 2 if available.  Within sandbox, I am unable to re-purchase a cancelled subscription within the app after successfully purchasing it the first time.  However, I can go into iOS and re-subscribe under my sandbox account in Settings/App Store/sandbox account/manage/subscriptions.
