If you lost your data and want to restore your backup files, please send a message to us, choose "Report a bug" -> "Data loss". We will look into your issue when we are available.
Data loss may involve differences in data schema versions across devices. Directly restoring a backup could potentially worsen the situation. Therefore, if you encounter this issue, please contact us.
If you haven't lost any data but just want to restore it to an earlier version, please also reach out to us. We can enable this feature for you!
