A. 1. Ensure you are saving changes: After editing a photo, make sure to tap 'Save' or 'Done' before exiting the editing screen. 2. Check storage space: Go to Settings > General > iPhone Storage and ensure you have enough space available. Low storage can prevent changes from being saved. 3. Restart the app: Close the app completely and reopen it to see if the changes are saved.

B. 4. Reinstall the app: If the problem persists, uninstall the app and reinstall it from the App Store to reset any potential issues.
