A. If the app freezes, try force-closing it. Double-tap the home button (or swipe up from the bottom on newer iPhones) to see all open apps, then swipe up on the Chase app to close it. Reopen the app to see if the issue is resolved.

B. Check for any available updates for your iPhone's operating system. Go to Settings > General > Software Update. Keeping your iOS updated can help improve app performance.
