A. 1. **Backup Your Vlogs**: Before updating the app, always back up your vlogs. You can do this by exporting them to your camera roll or another storage solution. 2. **Check for Recovery Options**: After an update, check if there’s a recovery option in the app settings or support section that might allow you to restore deleted content.

B. 3. **Contact Support**: While I won't suggest contacting developers, check the app's FAQ or help section for any known issues regarding updates and deleted content.
