I recently installed ios app and Mac app. Both worked for a couple of days. Then when I try to access on ios I get the message: “You cannot remove this file you do not have permission”. The ios app unlocked the vault, and everything was there, but trying to just look at a file resulted in the above message, ios is 15.1 and Monterey running on Mac. Tried rebooting the ios device but no luck.
Is it possible that you’re using the iOS app in read-only mode?
Edit: Ah, it’s probably this error: https://github.com/cryptomator/ios/issues/154 (fix should come out soon, sorry for that!)
Edit 2: Current workaround is: Delete the cache (in the Cryptomator settings) and try again.
