Show watch status of items in my Watchlist

After I add shows or movies to my Watchlist, it doesn’t let me know the watch status of any particular item. Possible suggestion is to have filter for played/unplayed items or maybe it get removed from the Watchlist once watched

All items in your Watchlist are considered “unwatched”.
Once you watch them in Plex or mark them as “watched”, they are removed from the Watchlist.

If this was true, I wouldn’t have posted it. Even after I have watched every episode in a particular Show or Movie, it remains in the Watchlist

Watched them where? If you go to another streaming service, Plex cannot know that you watched it. It simply cannot see what you do inside other streaming services. Universal Watchlist (Beta) | Plex Support

Same is true if you watched these items from your own Plex server, but didn’t change to the new metadata agents yet…
