I know this isn't a huge issue in the grand scheme of things, but it is pretty annoying. I've noticed that Plex seems to misattribute the episodes in my watch history when a show is ordered differently in my library than Plex's global episode order.
For example, I have some shows organized in different order (such as DVD order rather than airdate order.) This happened again recently: my watch history correctly shows that I watched Season 2, Episode 51 but the thumbnail/screenshot associated with that entry is for a completely different episode.
If I click the thumbnail in my watch history, Plex takes me to the show's global Plex page, where Episode 51 is a different episode because Plex is using its own episode ordering. If I then click that episode and select Where to Watch > My Library, Plex takes me back to Episode 51—but this time it's the correct episode, because my library is using DVD order.
So I think I understand what's happening: Plex appears to be recording the watched status based on the episode's position in Plex's global/metadata order, rather than the episode's position/order in my library.
The problem is that this makes Profile > Watch History inaccurate. I end up with a long list of entries showing the wrong episode thumbnails/titles for episodes I actually watched.
This also affects tv shows I add to my watch list. I go to my watch list, select the show , and it first goes to Plex's global page for that show ( not my library) and it shows all the "marked as watched" checkmarks beside episodes that are seemingly out of order . Of course, once I make a few clicks and work my way to my library, all is in alignment and marked as watched is correct.
I'm guessing there may not be much Plex can do about this, especially when libraries use different episode orders, but is there any way to prevent or correct this? Has anyone else run into the same issue?
