I have recently setup a user account on my plex server to allow them to log in and watch something and be able to keep track of what they watch and not effect my watch status.
How ever I found when I was setting up a smart collection for there shows (some we have in common) the watched status carried over to her log in.
Is there a setting I am missing? I really would like it if a show I watch before my user is not showing watched under there log in or visa versa.
By the way searching for what I am talking about is non existent practically as you get about watched status between servers. . . . . .
You could guide them to create their own smart playlists (or create a playlist for them). The creation is pretty much the same as for a collection but it will only apply to the respective user. Downside: you cannot use the same collection for all users but each needs their own playlists.
