Hunter2660's reply contradicts the description of the App on the Apple App Store, below is the relevant wording and by implication would allow the BT TV Box Pro to be used on one TV and the App with the Apple TV 4K on another TV and have access to all the channels subscribed to so for example that would imply SKY Cinema and SKY Entertainment if the "Big Entertainment" package was subscribed to.
BT TV customers can use the app to watch live channels and shows on demand in line with their TV subscription via smartphone, tablet and laptop wherever they are. All at no extra cost as part of your BT TV package.
