Got it on the Box Pro here - but it is the cut down version so is missing thet 26 live channel streams.
The live TV feature is currently available only on Amazon Fire TV, Android TV, Apple TV, Freesat, Now/Roku streaming players, Samsung Smart TVs, Sky Glass and Sky Stream puck, Virgin Media, Xbox One/S/X and Xbox Series X/S
@why_oh_why correct. and the cost for the premium subscription is the same as those who have access to the HD version too.
Itv are in a mess, more we complain the better chance of this getting fixed / enabled.
