Here's a breakdown of the problem:

  1. Running on Android Emulator: When attempting to run your application in Android Studio on an Android emulator, it functions without any issues.

  2. Running on Simulator (iOS): However, when you try to run the app on the iOS simulator, it fails to work.

  3. Running on Xcode: Surprisingly, if you open the application in Xcode and run it there, it functions correctly on the simulator. Yet, in Android Studio, the issue persists.

Many online solutions suggest accessing "Keychain Access > Login Certificates" and deleting all Apple certificates. You may have already tried these solutions on platforms like Stack Overflow and Apple communities, but they yielded no results.
