DV Black level issue with VUDU and Disney+ on xbox series x

I have this same issue and ONLY on my Xbox Vudu app, everything else streams fine but Vudu on Xbox has constant buffering on anything hdx and above, intermittent on standard. For me this is only happening on my series x version of the app, I have a one x, two iPads, an android tablet and Vudu works no problem no buffering can watch things all day, but as soon as I get on my series x and launch Vudu I can be certain it’ll ask me if I want to down grade quality to lessen buffering (and of course it’s worded to make me feel like it’s an issue with my isp) within the first ten to twenty min of watching something. It’s definitely an updated Xbox Vudu app issue, Since I can stream from my Vudu account flawlessly on any other device in my house.

I am currently still having issues with vudu on my xbox series x and s. Never had any issues before updating to new system. very aggravating.

I have XBOX series X VUDU Black screen issue ( app wont launch) since Late AUG 2021, there was an xbox update in OCTOBER introducing additional support and settings for Dolby vision and HDR and whatever that was made the VUDU app worked again, however it has been short lived as I have made a purchase on VUDU on 11/29 and now I get a black screen on xbox when launching, does this VUDU app not work with certain resolutions that fight tv and XBOX, it works on PS5 , it works through my SONY Television, I'm curious if the latest update that was pushed about a week ago has crippled the VUDU app again... any help or suggestions would be appreciated, so done with functionality not working with NEXT GEN tech, we can go to space but can't get an app to stream on a streaming device, very frustrated XBOX user....

I have vudu & flixster & both are linked to ultraviolet (also have cinemanow linked.), but I cannot watch vudu on flixster & vice versa. also, linked to disney through vudu & the disney movies are not on cinemanow, nor are any flixster movies on cinemanow.

I just wanted to add that I'm having the exact same issue on my Xbox Series X and I have W.O.W as my ISP, so Comcast is not the issue... This definitely seems to be an issue with the Vudu app for Xbox... Any updates on this?
