The Flutter project has integrated RevenueCat, and all Android configurations have been completed:
-
Installing the Android APK built locally via
flutter build --releasecan successfully open the Google subscription page, and clicking subscribe brings up the payment options. -
After uploading the AAB to the closed testing track and downloading it from there, opening the subscription page shows a gray paywall and displays the message:
"error 11: there was a credentials issue, check the underlying error for more details", and the subscription items cannot be displayed.
In RevenueCat’s dashboard, the following permissions are all correctly set:
-
Permissions to call subscriptions API
-
Permissions to call in-app products API
-
Permissions to call monetization API
So my question is: why does the paywall fail to load when using the second method, and where is the problem?
