Apple tv on samsung

Hi Bbbzrh,

Assuming you're referring to the TV app, try resetting it as outlined here:

• Reset the Apple TV app

If you’re having problems and the Apple TV app still doesn’t respond after restarting, try resetting the Apple TV app. When you reset the Apple TV app, all data is erased, including your accounts and configuration.

1. In the Apple TV app , navigate to Settings. 
2. Go to Reset, then select Reset. 
3. Resetting the Apple TV app restores it to original settings and removes your personal information, TV shows, and movies from the smart TV.

After resetting, if the issue persists, what specifically is it or is it not doing?

For example, does the app not open at all? Will it not play content? Does it not let you sign in?

Some additional details will help us better assist.

Take care.
