Sorry, but this menu thing beat me too. I am not expecting the three dots to morph into some other menu when I am in the settings menu but morph they did. So it seems I have backed up / restored and can take it from here...
Interesting that the backup clearly said accounts and settings, and ticked, but only the accounts seem to have made it as definitely many changed settings are on default and nothing listed in recent changes either, whereas the 4 has some there....
Edit: I am fully sorted now, but had to make another backup with just settings to get them to carry over, which the recent changes list didn't go but the changes did. I tried just selecting settings, or both. Got told settings had nothing to do and 8 accounts were duplicates so none created. Ok, so I made just a settings one and it worked. Using Dropbox if that is relevant.
