Playback stops on its own after a few minutes

[rado84]

Recently I bought a new phone - Nokia G21 and while all previous problems disappeared, a new one appeared. But IDK if it's Aimp bug or Android problem, that's why I am posting it here.

I run a playlist, it plays a few minutes and then suddenly stops. I discovered that if I pressed the power button once, so that the screen lits up, playback resumes. I don't even have to enter the pin to unlock the screen, it just has to be lit for playback to resume.

Any ideas why this is happening and how to fix it?

Temporary fix: stay at app when turning off screen.
Absolute fix:
1) turn off power saving for aimp.
2) turn off power saving in general.
3(?) turn off Duraspeed https://dontkillmyapp.com/hmd-global
