Unlike iOS, it seems to be difficult and complicated to find the way to delete the Apple TV apps.
Thanks for your helps.
At for me tvOS is much more easier to use then iOS. The thing makes users feel hard to handle Apple tv is the remote.
How to arrange, delete Apple TV apps?
Deleting an app from your Apple TV starts the same way: emphasize the app icon, then push and grasp the trackpad until the icon starts stirring. Then, push the Play/Pause button on the TVs remote. Verify that you would like to delete the app on the subsequent display of Apple TV.
