I have a Vizio 70 inch 4k 2018 tv. We have watched 100+ movies in 4k up to this point on vudu. Bought endgame today through the phone app in 4k. On the tv app it shows "you own this in UHD". However, the app will not play the movie in UHD. I checked the settings and it will no longer let me set UHD as default and no movies will play in 4k. Any advice?
