@pennywrites Right now (confusingly) the accounts don't really tie to your data at all so it really isn't meant to affect much. All your data is stored on your device and doesn't go anywhere. I'm looking into introducing encrypted iCloud Backups which should make it easier to backup your data.
That said, the latest update fixed the bug with the not being able to export a backup. Can you try exporting your data and recovering it on Mac (or somewhere else)? This should let you access a copy of your data on your Mac.
