Hi there! I understand that Gotham Sports is working perfectly on your iPhone but you’re having trouble with it on your Fire TV. Let's see if we can get it working again!

First, could you share if you're seeing any error messages on your Fire TV, or does the app simply not load? Additionally, have you tried any troubleshooting steps already, like restarting the device or uninstalling and reinstalling the app?

In the meantime, here’s a general troubleshooting approach you can follow:

1. Restart Your Fire TV: This can sometimes resolve temporary glitches. You can do this from the settings menu or by unplugging the device for a few seconds.

2. Check for Updates: Ensure your Fire TV is running the latest software version. Go to Settings > My Fire TV > About > Check for System Update.

3. Reinstall the Gotham Sports App: If those steps don't help, try uninstalling the app and then reinstalling it. You can do this by selecting the app, pressing the Menu button on your remote, and choosing "Uninstall". After that, go to the Amazon Appstore to download it again.

4. Clear App Cache and Data: If the app doesn’t launch properly, clearing the cache can help. Go to Settings > Applications > Manage Installed Applications > select Gotham Sports > and choose "Clear Cache" and "Clear Data".

5. Check Your Network Connection: Make sure that your Fire TV is connected to the internet. You can do this by going to Settings > Network and verify the connection status.

If you continue to have problems, I can look up more specific issues related to Firewall or ongoing service outages. Please let me know how it goes!
