Hi there! I see you're having trouble with the Newsmax app crashing on your Roku and smart TV while watching. Let's work together to get that fixed.

To start, could you tell me a bit more about when the app crashes? For example, does it happen right after opening the Newsmax app, during playback, or at random times? Also, are both your Roku and smart TV connected to the same network?

Meanwhile, here are some initial steps that usually help with this kind of issue on Roku devices and smart TVs:

1. Remove and Reinstall the Newsmax Channel/App:
- On Roku: Go to "Home," navigate to the Newsmax channel, press the star (*) button on your remote, and choose "Remove channel."
- Restart your Roku device from Settings > System > Power > System restart (if you don't see Power, just restart the device manually by unplugging it for 10 seconds and plugging it back in).
- After restart, go to Roku Channel Store and reinstall the Newsmax app.
This can clear any corrupted cached data that might be causing crashes.

2. Update Software/Firmware:
- Ensure your Roku and smart TV firmware are up to date. On Roku, go to Settings > System > System update, then check and install any updates.
- On your smart TV, check for software updates in the settings menu.

3. Check Your Internet Connection:
- Sometimes, unstable or slow Wi-Fi can cause streaming apps to crash.
- Try running a speed test to confirm your connection is stable.

4. Force Close the App (If your smart TV allows it):
- On some smart TVs, you can go to the app settings and force close the app before reopening it.

If you've already tried some of these, let me know which ones, and we can explore deeper fixes. Also, if there’s any error message appearing when the crash happens, please share that.

Would you like me to guide you through any of these steps?
