[Library rescans every time]

has somebody solved this?

I have the same issue, on stock firmware, Android 11

all permissions set correctly, if I go to settings, the correct folders are checked

sometimes the rescan starts automatically after a restart, sometimes the restart has to be done manually

Music files are all stored on SD card (but as said Poweramp does remember the folder locations correctly)

Complete re-install done, same behaviour

 

EDIT: just found the thread "S20 loses SD card access on each reboot (build 893)" maybe that helps
