I have a peculiar problem with a series episode. I started it accidentally and after about a minute, backed out and marked it as watched.
Now, every day, it comes back as unwatched and with the time stamp of where I left off. This happens on Roku, Chromecast (LG App), AppleTV and Web Player.
I have seen this behavior happen when there is a player that is paused/queued on that video. Have you tried checking all your devices to make sure the video is not paused or “queued” on a mobile device?
This issue has been low-key pestering me for months but after marking the same media item as read about 6 times in the past 2 days, I just did some searching and came across this thread. Checked my mobile device and sure enough that was it (it was paused, mid-playback)
Shouldn’t Plex be able to resolve this even if a media item is finished on a different device? i.e. (timestamp for mark as viewed) > (timestamp of last progress checkpoint) and the in-progress media item is cleared from the device with older info.
In other words, are we saying that today, if I watch a single media item split between multiple devices, that Plex will always take the earliest playback progress among those devices and mark the item based on that?
I would agree. What I think is happening is that the media position on the mobile client is being sent to the server without first checking to see if has been superseded by another device.
I don’t think is has to do with earliest playback I think it has to do with how the device checks in and updates the server. If you fully watch something on device 2 but then device 1 checks in after to say that you were in the middle of watching it… technically when device 1 checks in and updates the server, it happens last (the newest timestamp). Thus you see it partially unwatched again. It maybe more complicated than that but that is just my take on it.
