The Cupertino technology giant is currently testing the upcoming tvOS 12.3 update that includes an overhauled TV app with a new built-in Channels subscription feature.

The overhauled TV app is coming via tvOS 12.3 and iOS 12.3

This will let customers subscribe to channels such as Showtime or Stars directly in the TV app, then watch those shows without having to use the networks’ official apps for tvOS at all.

The Channels feature will also launch in the TV app for iPhone and iPad with iOS 12.3.
