@TeamYouTube hello! I'm having problems playing paid movies on YouTube through my Fire TV YouTube app. Sound comes through fine but video is frozen. Regular videos play fine. I did try to reset and didn't help.
FWIW -- probably nothing -- this same thing happened for quite a while in the YouTube app on Comcast's Xfinity platform. Tried watching purchased videos through YouTube one day, on the cable box, and it suddenly worked.
