I paid for Boost as I watch through the Xbox app on a top of the range TV, and was wondering why BT sport Ultimate looks so much better than sky sport, so I googled it and found this thread... Come on Now TV, this is ridiculously poor on your part, please sort it out.
Didn't you get the memo.
Boost is now available on Xbox One (though the only downside it will not play 50fps for sports).
Hopefully you are not a NowTV Combo customer on the old legacy account, that still can't get Boost on any devices 😠.
If you signed up via the website and the Boost Pass doesn't kick in straight away (could take up to 3 hours via your account on the website) then sign out of the NowTV App on your Xbox One and sign back again to trigger the Boost Pass.
Also if you are not getting 5.1 surround sound, have a read of this link below.
