Okay, so I was watching a movie directly on the plex server on my computer, then I started watching later on the roku. Now whenever I go into plex either on the roku or computer, it says it’s back where I left off. I choose mark as played but it keeps popping back up on both devices.
In general, never Pause a video in Plex for longer. Always use the Stop button. Your playback position will be stored anyway, so you can resume the video later - even on a different device.
