A Plexie in another thread asked to vote for it in the Feature Suggestion section.
The new video player in the Adroid (and derivates) Plex client software is missing the feature. It is not seen as bug, so I suggest to upvote the feature suggestion here:
And as you can see in the referred thread, Plex buddies do not know that kind of problem very well - it’s definitely worth a read… and if you want it “fixed”… vote for it.
