Excellent investigating. Nice catch on narrowing it down to the cinema trailers. Possible related post?

Cinema Trailers from new & upcoming movies not working

Just got Plex Pass and switched on cinema trailers from new and upcoming movies. When I try and play a movie, I just get a never ending orange loading circle. I tried turning the feature off and use only local trailers from unwatched movies, and that works fine. But as soon as I turn on the new/upcoming trailer option, orange loading circle again.
