Clearly not built for Android 11. Permissions configured the way that way too confusing article (most of us end users are not developers, lines of code are meaningless to us) indicates generate "failed to" actions. Adding insult to injury, Google branded file management apps can move files this app "fails to" move. This app works great on my Android 10 and older devices, but it clearly needs a lot of work to deliver the same streamlined, quality, and expected experience on newer Android devices.
