A. 1. Check your internet connection: Ensure you have a stable internet connection, as progress may not save if the app cannot sync with the server. 2. Enable cloud saving: If the app has an option for cloud saving, make sure it is enabled in the settings. This can help save your progress across devices. 3. Regularly save your progress: If the app allows manual saving, make it a habit to save your progress frequently.

B. 4. Clear app data: Go to Settings > Apps > Puzzle Page > Storage > Clear Data. Note that this may reset your settings, but it can resolve issues with saving progress.
