Hello,
the trailers aren't working properly anymore since the last update.
It always plays the trailer in SD. Also, some trailers were unwatchable because of stuttering and always pausing (with a big grey/black play button appearing on screen). It's impossible to change the quality. I know this sounds like a bandwidth problem but the TV is connected via ethernet and playing the same trailer on the YouTube app is working flawlessly in high quality up to 4k.
It also looks like it's using some kind of interface suited for mobile devices. There are buttons on-screen you can simply not select with the remote like "watch later" or "share" in the top right and when pausing there is even an X to close the "more videos bar" at the bottom.
I also prefer a seamless integration but currently, it makes the trailer feature not a fun one on my Android TV.
I've sent a report from within the app, I hope that will help to narrow down the problem.
