EAS Build] AsyncStorage and SecureStore Data Empty After Updating From a Classic Built App (SDK 45) to an EAS Built App (SDK 47)

This issue is pretty old. There was a time (can’t remember off hand what the Expo SDK versions were, but definitely a lot older than SDK 45) when the default location for AsyncStorage was moved or something like that, so the original issue might have been related to that.

So it might be worth creating a new issue with your reproduction example.
