A. 1. Ensure you are logged into your account: Check if you are logged into your Google Play account or Facebook account, as this is often required for saving progress. 2. Check for app updates: Make sure you are using the latest version of the game, as updates often fix bugs related to saving progress. 3. Clear app cache: Go to Settings > Apps > Merge Mansion > Storage > Clear Cache. This can help resolve issues with saved data.

B. 4. Reinstall the app: Uninstall Merge Mansion and then reinstall it from the Google Play Store. This can help reset any corrupted files that may be preventing progress from being saved. 5. Check device storage: Ensure that your device has enough storage space available, as insufficient storage can prevent the game from saving progress.
