I’m running a Plex server on a Synology NAS, I’ve got OS X, Roku, IOS, Android, and Amazon Fire Stick clients connecting.
I’m finding that movie trailers and pre-rolls are working inconsistently. Sometimes I get them, sometimes I don’t. My system clock times are all correct.
I’ve seen problems reported before, but they were years ago, and most of those topics have been closed.
Usually each client have their own configuration on if / how many trailers to play.
Should be something like Settings > Experience > Cinema Trailers on most of them.
e.g. for Roku, iOS…
Server enables if you want to support trailers/prerolls at all and for what libraries. Clients decide if / how many trailers they want to see before a movie.
That makes sense to me, given I definitely want to see some fancy preroll on the big screen with my home theatre enabled – not so much on a mobile device / on the road.
