Answer 1

Check manually Your app like @dmle said,

1. Open app on Android
2. go to terminal, console, command line (whatever)
3. Adb should be installed,
4. input in termninal adb shell dumpsys window windows | grep -E 'mCurrentFocus|mFocusedApp

The command will provide current package & activity.

Maybe developers changed You package id.
