A. 1. Restart the App: Close the MeMi Message app completely by swiping it away in the app switcher. Then, reopen the app to see if the issue persists. 2. Update the App: Go to the App Store, tap on your profile icon at the top right, and scroll down to see if MeMi Message has an available update. If so, tap 'Update'. 3. Clear Cache: If the app allows, go to Settings within the app and look for an option to clear cache or data. This can help resolve performance issues. 4. Reinstall the App: Delete the app from your iPhone and reinstall it from the App Store. This can fix corrupted files that may be causing crashes.

B. 5. Check for iOS Updates: Go to Settings > General > Software Update and ensure your iPhone is running the latest version of iOS, as updates can fix compatibility issues.
