I've noticed that the trailer icon is showing up for movies in the single item view in the Android app (v3.1.80) and web client (likely others) when I don't have local trailers for them. When I click the trailer icon, Emby (server v4.5.4.0) tries to playback youtube trailers. I don't have the trailers plugin installed, and I don't want Emby to ever try to play anything that isn't *my* media stored locally. And I don't want to see a trailer icon unless *I* have the trailer for the movie
