If you've lost data and need to restore from a backup, contact us by sending a message through Report a bug → Data loss. We'll review your issue as soon as possible.
Restoring data yourself may cause issues if your backup files and current data have different schema versions. To avoid making things worse, please reach out to us for assistance.
If you haven't lost data but want to revert to an earlier version, contact us, and we'll enable this feature for you!
