Hi there! I see you're experiencing issues with the Newsmax app on your device. Could you tell me a bit more about what exactly is not working? For example, is the app not opening at all, crashing during use, showing error messages, or something else? This will help me guide you better.

While I wait for your details, here are some basic steps you can try on your Android device with WebKit and Android 10:

1. Clear Cache and Data:
- Go to Settings > Apps > Newsmax.
- Tap on Storage.
- Clear cache first, then clear data.

2. Restart Your Device:
- Sometimes, a simple restart can refresh system processes and resolve many app issues.

3. Update the App:
- Check Google Play Store to ensure your Newsmax app is updated to the latest version available.

4. Reinstall the App:
- Uninstall the Newsmax app completely.
- Restart your device.
- Reinstall the app from the Google Play Store.

If you have already tried these, please let me know, and we can dive deeper into troubleshooting or look into network and account-related factors.

Are you currently getting any specific error messages or codes when attempting to use the app? That info would also be very helpful.
