[Bug] Pinning not working (Android 12)

Hi, I am using your beautiful gallery (the only good looking open source) sins the past two weeks on a Pixel 5 (with custome Rom: CalyxOS). The app works great but the pinning (hiding) doesn´t work. It is possibly a Android 12 issue (because the last update is from 2020)
I woud love to see active devolopment again...
