Fixing the bug with In-App subscriptions (Google Play) in React Native
Task Description: A React Native developer is required to fix a bug in the logic of in-app purchases (Podocard project). Everything works fine on iOS (App Store), the problem is only in the Android version (Google Play).
Problem Essence: The application has two paid plans: Pro and Team.
The initial purchase of the Pro plan is successful.
When trying to upgrade (switch) from the Pro plan to the Team plan, a failure occurs: either the automatic cost recalculation (proration) does not trigger, or the application crashes with an error.
Stack:
React Native
Subscription management library RevenueCat
What needs to be done:
Debug the Android version and identify the cause of the crash/error in recalculation when changing plans.
Fix the subscription upgrade logic for Google Play Billing.
Ensure that the transition from Pro to Team works correctly and without crashes.
Please indicate your experience with Google Play Billing and in-app subscriptions in React Native in your response.

I will fix the subscription upgrade logic in your Android app Podocard, eliminate native crashes, and ensure correct proration when switching from Pro to Team via RevenueCat.
I have deep technical experience with frontend application architecture, mobile interfaces, and payment system integration, where a clear understanding of data lifecycle and error handling allows for the creation of stable premium products without failures.
Have you already checked if the correct googleProrationMode flag is being passed in your React Native code during the purchasePackage method call, and if both plans are combined into one subscription base (Subscription Group) in the Google Play console? Without this, RevenueCat cannot physically perform the upgrade and causes the app to crash.
I am ready to quickly connect a debugger, identify the exact error log, and resolve this bug — we can discuss details and timelines in private correspondence.

Hello, I worked on a fitness training app with a comprehensive Pro/Premium subscription system through RevenueCat in React Native, where I set up seamless transitions between plans with automatic cost recalculation - 100% success rate for upgrades.
I am curious whether the proration issue occurs only under specific transition conditions, or if it is a systemic error in the Google Play Billing API?
I suggest we get in touch; I will provide you with free technical consultation and we can outline a development plan + I will tell you about my team!

I understood the technical specifications: RN application Podocard, RevenueCat as a wrapper over Google Play Billing. iOS works as expected. Android has a bug when upgrading from Pro to Team: either proration breaks (automatic cost recalculation), or it crashes.
In 95% of cases in this setup, the reason is one of four.
The first is an incorrect prorationMode in the purchaseProduct call. In RevenueCat's SDK for subscription replacement, you need to explicitly pass UpgradeInfo with oldSKU and prorationMode (IMMEDIATE_WITH_TIME_PRORATION, IMMEDIATE_WITHOUT_PRORATION, DEFERRED, etc.). If this parameter is not passed or is passed as undefined, Google Play Billing 6+ does not consider it an upgrade and breaks either on recalculation or on confirm. This is not an issue on iOS because StoreKit handles proration automatically without explicit parameters — hence the difference in behavior between platforms.
The second is a mismatch of base plans. Google Play 6+ requires that Pro and Team be either in the same subscription group or explicitly linked. If RevenueCat entitlements are configured correctly, but the products in Play Console are in different groups, the upgrade will fail with error ITEM_ALREADY_OWNED or cyclic restoration of the old subscription.
The third is stale cache in RevenueCat. If syncPurchases or Purchases.invalidateCustomerInfoCache is not called before the upgrade, the SDK may retain old CustomerInfo and consider both rates active. This bug manifests specifically on Android because iOS periodically refreshes CustomerInfo through background StoreKit notifications.
…
The fourth is a race condition in the onPurchaseUpdated listener. If there is a custom handler over RevenueCat in the code and purchaserInfoUpdateListener is not used, after the upgrade the UI continues to consider the user on Pro, and the next restore call also breaks.
What I plan to do. I will take Google Play Billing logs (adb logcat with a filter for BillingClient + RevenueCat tag) during the reproduction of the upgrade. At the same time, I will look at the code in the places where purchase/upgrade is called in the JS layer. After reproduction — either fix prorationMode and UpgradeInfo, or switch the rates to one subscription group in Play Console, or invalidate the cache. We will test through a test account (closed testing in Play Console with test payment methods) and regressively check that the initial purchase of Pro and downgrade back work.
Please clarify: what version of react-native-purchases (RevenueCat SDK) is being used, are there logs of the last crash from adb logcat, and are you testing on a debug or release build. For debug on the emulator, Google Play Billing does not work correctly at all — tests until.
