A. 1. Ensure stable internet connection: A stable connection is crucial for saving progress. Check your Wi-Fi or mobile data before playing. 2. Clear app cache: Go to Settings > Apps > Merge Mansion > Storage > Clear Cache to help resolve any issues with saving progress. 3. Log into your account: Make sure you are logged into your Google Play or Facebook account to ensure your progress is saved online.

B. 4. Reinstall the app: If progress resets continue, uninstall and reinstall the game to reset any corrupted files. 5. Check device storage: Ensure your device has enough storage space available, as insufficient storage can lead to progress not being saved.
