Xbox360 needs my Plex Pass account? (No child accounts yet?)

My teenager uses his xbox 360 in his bedroom to access my Plex server, but he needs to use my Plex Pass account to do so.

 

It's not a huge deal, but can I make a sub account (or child account) under my Plex Pass, so that he can use my Plex Pass account, but have his own account name?

 

The reason I ask is that he watches TV shows and it marks them as watched and it makes it confusing when I watch Plex in the front room.

 

Thanks for taking the time to read this.  

it Doesn’t work with Managed users yet , but if you give him a regular free plex accountshare the libraries you want and then add that account to your Plex Home he will be able to use the xbox 360 app. when the xbox app shows him the PIN he will need to go to https://plex.tv/pin and sign in with his account an enter the pin to connect it
