I occasionally watch things streamed from my server on my bus ride home on an evening (using 4G). If I’m only half way through the show when I arrive home I continue watching on my Apple TV4K from where I left off. Once the show is finished Plex marks it as played and I’ll maybe watch something else. However, the next time I star Plex 9n my Apple TV or any other device, the show I was watching on the bus is back on the watch list as part watched, to the point where I left off on my journey.
I found the only way to stop it is go go back to my iPhone and mark it as pkayed there too. Is this a bug?
