All of our other apps work on our SONY TV but not Apple TV. Ideas?

Thanks for reaching out SarahFoulger,

It sounds like you're having trouble launching the Apple TV app on your Smart TV. We can help.

A good place to start is with these steps to 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.

Hope that helps.

Take care.
