The backup on this app is USELESS. To restore a backup this needs to be done when first installing the app, and thanks to a dark pattern this option is a tiny text link on the startup screen (no button for it). If you sign in first you've had it, when you switch on backups after signing in it replaces the original backup!! And if you do manage to restore a backup, it asks you to scan the QR codes again!! THAT'S THE WHOLE POINT OF THE BACKUP!!!!
