A. 1. Save templates: Before editing, save your favorite templates to your device or within the app if possible. This way, you can easily access them later. 2. Check for updates: Ensure that you are using the latest version of Meitu, as updates may fix bugs related to disappearing templates.

B. 3. Report the issue: If templates continue to disappear, document the steps leading to the issue and check online forums for similar experiences. This may help identify a pattern or workaround.
