Since recent Android updates my termux setup hasn't been able to access other application's data. I use rsync via that for backing up content, it still works for things like camera output, but not things like the files & config from my podcast app.

Though it turns out I've been negligent and not noticed the Play installed versions are no longer maintained, so they may have worked around whatever the issue is. I must get around to reinstalling via f-droid...

I can confirm that the F-Droid version has fixed this issue a while ago.

Hmm. Removed and reinstalled from f-droid and android/data is still inaccessible. Will do a bit more research and see if there are known problems with it on my device...
