Hi there! I’m sorry to hear about the trouble with the Newsmax app shutting down on your Firestick. That must be really frustrating. Let’s try to resolve this issue together.

First, let’s go through a few troubleshooting steps:

1. Restart Your Firestick: Sometimes, a simple restart can resolve app issues. Just unplug your Firestick from the power source, wait about 30 seconds, and then plug it back in.

2. Clear App Data and Cache:
- Go to Settings on your Firestick.
- Select Applications.
- Then, choose Manage Installed Applications.
- Find the Newsmax app in the list, click on it, and select Clear Cache and then Clear Data.

3. Check for Updates:
- Still in the Settings menu, go to My Fire TV.
- Select About and choose Check for Updates. Make sure your Firestick is running the latest software version.

4. Reinstall the App:
- If the above steps don’t work, you might need to uninstall and then reinstall the Newsmax app:
- Go to Settings, select Applications, then Manage Installed Applications, find Newsmax, and select Uninstall.
- After uninstalling, go to the Amazon App Store and reinstall the Newsmax app.

Could you try these steps and let me know if you’re still experiencing the issue?
