Hi there! I see you're having an issue where the NFHS Network app on your iPhone loads the game but then the screen goes black. Let's work together to get this sorted out.

First, just so I understand better:
- Does the audio for the game continue playing while the screen is black, or is there no sound either?
- Is this happening with all games or just a particular one?
- Have you tried any troubleshooting steps so far, like restarting the app or your phone?

Meanwhile, here’s a straightforward approach to start resolving this:

1. Close and Reopen the App: Double-press the home button (or swipe up from the bottom on newer iPhones) to see the app switcher. Swipe the NFHS app off the screen to force close it, then reopen it.

2. Restart Your iPhone: Sometimes a simple restart clears up temporary glitches.

3. Check for App Updates: Go to the App Store, tap your profile icon, and see if there’s an update available for the NFHS Network app.

4. Reinstall the App: If updates don’t help, deleting and reinstalling the app can remove any corrupted data that might be causing the black screen.

5. Check Network Connection: A stable internet connection is essential. Try switching between Wi-Fi and cellular data to see if the issue persists.

6. Clear Cache or Data: iOS apps don't have a direct cache clear option, but reinstalling effectively does this.

If these steps don’t fix the black screen, please let me know how the app behaved after trying them. If audio continues but the video is black, it might be a playback issue needing advanced troubleshooting.

I’m here to help you all the way! Are you able to try these first and share what happens?
