Hi there! I'm here to help you with your FloSports freezing issue on your smart TV. It sounds like you're experiencing interruptions after 30 minutes, leading right back to regular YouTube TV programming. Let’s work through a few steps to see if we can resolve this.

1. Restart Your TV: Sometimes, simply restarting your television can fix minor glitches. Power off your TV, wait for about 30 seconds, and then turn it back on.

2. Check Your Internet Connection: Slow or unstable internet speeds can lead to streaming issues. Make sure your smart TV is connected to a reliable Wi-Fi network. You can run a speed test to confirm your internet speed is sufficient for streaming.

3. Update the App: Ensure that the FloSports app is updated to the latest version. Sometimes updates fix bugs that could be causing the freezing issue. Check in your TV's app store for any available updates.

4. Clear App Cache: If your TV allows it, you may want to clear the cache for the FloSports app. This can sometimes improve performance. This option is often found in the settings menu under applications.

5. Check for TV Software Updates: Make sure your smart TV's operating system is up to date. Manufacturers frequently release updates that can enhance performance and fix bugs.

6. Reinstall the App: If the problem persists, try uninstalling the FloSports app and then reinstalling it. This can help clear out any corrupt data that might be causing issues.

7. Use an External Device: If you’re still experiencing problems, consider using a streaming device (like a Google Chromecast or Fire Stick). Sometimes, third-party devices can handle apps better than built-in smart TV applications.
