A. Ensure that your game is connected to a stable internet connection, as progress might be saved to a cloud server. Check your device settings to confirm that iCloud or any other cloud service is enabled for the app. Regularly back up your game data manually if the app provides such an option. If not, consider taking screenshots of your progress as a last resort.

B. Check if the app has an option to save progress manually. If so, use it frequently, especially before closing the app. Also, avoid force-closing the app, as this might interrupt the saving process.
