Cannot remove an Xbox 360 user from my Plex server

A while back I gave a friend of mine access to my Plex server. The Xbox 360 app gave me a plex code which I gave access by adding it to plex.tv/pin.

Now there is no way to remove him from my server. I go into devices menu within plex settings and remove him from deleting Xbox 360 withint the Xbox section. AND guess what he still able to connect. I deleted the Xbox access over and over and he kept saying accessing my server. I even disable DLNA and still have the same issues. When the Xbox user streams from my server and I check the activity it doesn’t display a plex user.

I see someone just posted a simulator issue as me on this forum. I guess it’s a bug
