Hi! I’m sorry to hear you’re having trouble logging into the OANN app on both your iPhone and Samsung smart TV. I’d like to get a bit more information to help you best.

1. When you try to log in on your iPhone, do you get an error message or does the app just not respond?
2. Are you able to access other apps on both devices without issue?
3. Have you recently changed your password or subscription details for OANN?
4. Is the OANN app updated to the latest version on both your iPhone (iOS 16.7.11) and your Samsung TV?

Meanwhile, here are some initial steps you could try on both devices:

On your iPhone:
- Make sure your app is updated. Go to the App Store, tap your profile, and update OANN if available.
- Restart your iPhone to clear temporary glitches.
- Check your internet connection (Wi-Fi or mobile data).

On your Samsung Smart TV:
- Power cycle your TV by unplugging it for 30 seconds and plugging it back in.
- Check for any available firmware/software updates on your TV via Settings > Support > Software Update.
- Delete and reinstall the OANN app to ensure the latest version is installed.
- If that doesn’t work, try resetting the Smart Hub on your TV (usually under Settings > Support > Self Diagnosis > Reset Smart Hub).

If your credentials are being declined, please double-check by logging in on a web browser to verify your username and password are correct. Sometimes typing errors or expired subscriptions could cause login failures.

Let me know what you observe with these steps, and if you get any specific error messages, please share them. That way, I can help narrow down the cause further!
