A. Check the app settings to see if there is an 'Undo' feature that can be disabled or adjusted. Sometimes, the app may have a sensitivity setting that can be modified to prevent accidental undos. Additionally, ensure that you are not inadvertently tapping the screen in a way that triggers the undo function. If the issue persists, try reinstalling the app to reset any corrupted settings.

B. Regularly save your work by exporting your journals or notes to a different format (like PDF) or to a cloud service. This way, if content is lost, you can recover it from the exported files.
