A. To prevent loss of progress when switching devices, ensure that you are logged into the same Apple ID on both devices. This allows your game data to sync through iCloud. Go to Settings > [Your Name] > iCloud and make sure that 'iCloud Drive' is enabled for Clumsy Ninja. If you have previously backed up your game data, you can restore it by downloading the game on the new device and logging in with the same Apple ID.

B. If iCloud syncing is not working, consider using a third-party app that can back up your game data. Look for apps that support game data backup and follow their instructions to save and restore your progress.
