A. 1. Close other applications: Double-click the Home button (or swipe up from the bottom on iPhone X and later) to view all open apps. Swipe up on any apps you are not using to close them. This frees up memory for Subway to function better. 2. Restart the app: Force close the Subway app by swiping it up from the app switcher, then reopen it. This can help reset any temporary glitches causing the freeze. 3. Update the app: Go to the App Store, tap on your profile icon, and scroll to see if Subway has an available update. Keeping the app updated can fix bugs that cause freezing.

B. 4. Check your internet connection: Ensure you have a stable Wi-Fi or cellular connection. If the connection is weak, try switching to a different network or resetting your router.
