A. 1. Check Your Credentials: Ensure that you are entering the correct username and password. If you have forgotten your password, use the 'Forgot Password' feature to reset it. 2. Reinstall the App: Delete the CardValet app from your device and reinstall it from the App Store. This can help resolve any issues caused by the update.
B. 3. Check for System Updates: Go to Settings > General > Software Update to ensure your iPhone is running the latest iOS version, as compatibility issues can arise with outdated software.
