Hi there! I understand your NFL app on your iPhone is stuck loading and won’t turn on. Let’s work through a few steps together to get it up and running smoothly.

Here’s what you can try:

1. Check for updates:
- Go to the App Store and see if there’s an update available for the NFL app.
- Also, make sure your iPhone’s iOS is up to date (you mentioned it’s on 18.6.2, which is pretty recent, but it’s good to double-check).

2. Restart the app:
- Close the NFL app completely by swiping it away from the app switcher.
- Then open it again and see if it loads properly.

3. Log out and log back in:
- If the app opens to some extent, try logging out of your account and logging back in. Sometimes the session just needs refreshing.

4. Check location permissions:
- The NFL app often needs location services enabled. Go to Settings > Privacy & Security > Location Services, make sure Location Services is on, and scroll to the NFL app to set it to "While Using the App" or "Always."

5. Uninstall and reinstall the app:
- Press and hold the NFL app icon and select “Remove App” to uninstall it.
- Restart your iPhone, then go back to the App Store and reinstall the NFL app fresh. This can clear out any corrupted data or caches.

6. Restart your iPhone:
- A simple restart can often resolve loading issues by refreshing your device’s memory and network connections.

Give these steps a try and let me know where you get stuck or if the app still doesn’t load after this.

If you’ve already tried any of these, please tell me which ones so I can help you further with deeper troubleshooting! Are you okay with trying these first?
