It's been said a hundred times already but they evidently aren't listening.
Sky, please, sort it out. I can't fathom why it would present such a challenge to add subtitles to all of your broadcasts but the situation with House of the Dragon (and most/all UHD downloads in my experience) is particularly absurd. The subtitles exist! They are on the HD version already. It's not like we are demanding anyone to work overtime to create them from scratch - just copy them across and make them available in the UHD version as well! This surely can't be some huge technical hurdle.
It feels as a UHD subscriber that I am paying extra for less.
