A. Ensure that your iPhone is running the latest version of iOS. Go to Settings > General > Software Update to check for updates. Keeping your device updated can resolve compatibility issues that may cause crashes.

B. Try uninstalling and reinstalling the app. This can clear any corrupted data that may be causing the crashes. To do this, press and hold the app icon until it jiggles, tap the 'X' to delete it, and then reinstall it from the App Store.
