The update copied my logins successfully, but it destroyed my sync settings.
Now I can't set up WebDAV sync again. It says it's "Authenticating..." for about half a minute, then it gives me an error saying "Could not connect to specified WebDAV folder. Check your usename and password.". There's nothing wrong with the input (URL, Username, Password), I tested them on Enpass on Windows, and I also tested with other WebDAV apps, no problem.
