The mobile app is straight up terrible especially on Android it is much better on iOS my iPhone XR with a 720p LCD Screen shows support for Dolby Vision & 5.1 Audio but all I see on my OnePlus 7TPro is HDR & nothing else no Dolby Vision or 5.1 or Atmos badge, my display panel is set to QHD+ 1440p & the maximum playback resolution is still FHD 1080p despite paying for the premium most expensive plan. I've never seen the Ultra HD badge on the phone, YouTube offers 8K option on their app...
