When doing a factory reset because of whatever reason, this becomes an issue as well. You cannot take screenshots of the bulk export QR-Code on Android because of FLAG_SECURE, so you need to work around that and take a photo of the screen with a different device to import from later.

Also, as of last week, there existed an issue with special characters when trying to import and the app would just freeze or not recognize the QR code pattern at all, so you better had backups of all your secret keys.

Both issues made me switch to Aegis and appreciate my past self backing up the secrets with KeePassXC.
