Hi there! I see you mentioned that the Tim Hortons app froze on your iPhone. That must be inconvenient. To help you better, could you tell me when it froze? For example, did it happen right after launching the app, during an order, or when you tried to access a specific feature?

Meanwhile, here are some initial steps we can try to get it working again:

1. Force close the app: On your iPhone, swipe up from the bottom (or double-click the Home button on older iPhones) to open the app switcher. Find the Tim Hortons app and swipe it away to close it fully. Then reopen the app.

2. Restart your iPhone: Sometimes restarting clears temporary glitches. Just press and hold the side button and volume button until the slider appears. Slide to power off, wait a few seconds, then turn it back on.

3. Check for app updates: Go to the App Store, tap your profile icon, scroll down to see if Tim Hortons has an update available. If yes, update it to the latest version.

4. Check your internet connection: Ensure you have a stable Wi-Fi or cellular data connection, as the app needs that to load properly.

5. Clear app cache (if applicable): Though iOS apps don't usually have direct cache clearing, uninstalling and reinstalling can often help.

If you’ve already tried these or the app still freezes, please let me know which steps you’ve attempted and if there are any error messages or specific behavior when it freezes. That way, I can guide you further.

Are you comfortable trying these steps now?
