A. 1. Check for backups: If you have previously backed up your data using Google Drive or another service, you can restore your information. Go to 'Settings' > 'Accounts' > 'Google' > 'Backup' and see if there is an option to restore.
2. Re-login: Sometimes, logging out and back into your account can refresh your data. Open the app, go to 'Settings', and log out. Then log back in to see if your information reappears.
