That’s all that’s missing really and for me would make it the complete streaming box
Just emailed them and they said:- Whilst All 4 is not currently available via a dedicated Apple TV app, we are working on this and hope to be able to provide in the near future.
Apparently it’s in the works
I only listed native apps.
twitch is available on there. There are a few apps for it. Twitchy is the most popular i think. You can also get Hotstar (from the India store) with means you can watch EPL / F1 for about £2.30 a month
