Im sure you appreciate what you are describing is "full AppleTV TV app integration"
Sure - iPlayer, ITV Hub, All4, My5, UKTV Play, Disney+ and Amazon Prime video all play nice with it.
However, thats not a given across the board. Netflix is the obvious exception as they refuse to fully integrate which is a real shame. Their content can be found in search, and even added to 'up next' but doesnt work fully as the others do.
When the updated NowTV app is launched it is rumoured it might also include full integration which is great.
Wow, is this really happening? They have tweeted a couple of people to say it is!
I feel like we should all have some sort of celebration, but I guess a street party is out of the question at the moment.
