Android 11 restricts access to system files like the Android folder files but the "files" application allows access to them so why not combine the two?
It's just a suggestion, thanks anyway for developing this application.

It's not the "Files app" that gives access, but targeting android 11 and setting a specific flag. That work is tracked in #1721 and I'll close this issue - you can follow that one for progress.
