Recently The Plex Roku client (and possibly others) have been truncating the playback of the last 1 minute+ of shows. On movies with 3 minutes of credit this isn’t a problem. On 30 minute TV shows that are actually 22 mins. minus the commercials and opening scenes this is 1/7th of the show and many times a key last minute teaser is not played (missed).
This only started happening recently either the last or last two updates.
