Hello
I'm developing a React Native application and I added IAP (like subscriptions) to my app. For it I user react-native-iap, I suppose It's the most common library to integrate in-app purchases. So, I created 3 subs on App Store Connect and tested it on the iOS simulator. Firstly I was receiving the empty array instead of subs data, but when I have been add StoreKit to my project I became to receive an appropriate subs data with all corresponding information. Moreover, I could successfully subscribe on them.
But, when I released app on the TestFlight for internal testing I forced with the familiar issue, I received an empty array.
In conclusion, on the debug version everything works (subscriptions data returns), but on the release I can't to receive the same result.
