A. 1. Check your account: Ensure you are logged into the correct account where your watchlist and history are saved. Sometimes, users may accidentally log into a different account. 2. Clear app cache: Go to 'Settings' > 'Apps' > 'AniDub Max' > 'Storage' > 'Clear Cache'. This can help restore your watchlist and history if they are not displaying correctly. 3. Reinstall the app: If the issue persists, uninstall and reinstall the app to see if that restores your watchlist and history.
