Delete app on Apple TV

Arrange and hide apps on your Apple TV - Apple Support

There are 2 methods of deleting an app.

Select the app on the main screen and press and hold the touchpad until the app icon wobbles. Press the play/pause button and choose delete from the menu that appears.

Navigate to Settings > General > Usage > Manage Storage, scroll and select the the trash can to the right of the problematic app and choose delete from the menu that appears.

I’m not really sure if there is any difference between the two methods but there have been some suggestions that the wobble method has resulted in some app data being left behind and ultimately causing an issue when the app is re-installed.

To re-install an app navigate to the App store > purchased, scroll down and select the app and then navigate to and select the install option.
