When the application is running on Android (11)
When you open Google Play, you cannot select any menu (you just click on the smartphone screen and nothing happens), but when you stop the application, all the menus in Google Play "come back to life" and can be selected by tapping the screen with your finger.
The same behavior has also been observed in some other applications.
I hope the developer can fix this somehow, because you have to first close the app, then work in the Google Play menu, and then reopen it.
But because of the minimal battery and smartphone resource consumption, I don't want to give up this cool app.
