Hi there! I understand you’re facing an issue with the Newsmax app on your Samsung TV with the Firestick. It can be quite frustrating when an app keeps crashing and taking you back to the home screen. Let's try a few steps to fix that together!

1. Force Stop the App:
- From the Firestick home screen, navigate to Settings.
- Select Applications.
- Choose Manage Installed Applications.
- Find the Newsmax app and select it.
- Select Force Stop to close the app completely.

2. Clear Cache:
- After force-stopping the app, select Clear Cache to remove any temporary files that might be causing the issue.

3. Restart Firestick:
- Once you've cleared the cache, it’s a good idea to restart your Firestick. You can do this by going to Settings, then My Fire TV, and selecting Restart.

4. Reinstall the App (if the issue persists):
- If you still encounter the same problem, it might help to uninstall the Newsmax app and reinstall it. You can do this by going back to Manage Installed Applications, selecting the Newsmax app, and choosing Uninstall. After uninstalling, go to the Amazon Appstore and reinstall the app.

Give these steps a try, and let me know how it goes. If the problem continues, we'll look into further solutions together! Are you satisfied with the solution I provided?
