Thanks for the reply, I have already set up a new user for him in plex which works fine in web but in the Xbox app I cant find a way to log him into the plex app as him (he is the only user on the Xbox) when I installed the app and connected the server it has automatically showing him all films as me and I can choose a different user.
When you enter the PIN the Xbox shows you on your computer, it connects to whatever account you were signed in on that computer.
If you go to the XB1 settings in the app, you can check which user it's connected to and 'Sign Out'. After that you should be presented with the PIN screen again. If you are signed in as your son on a computer on plex.tv, then you should enter the PIN there.
There's more hoops than we'd like, but that should work. Thanks!
Right, I found the setting which I signed out the user but it does not give me the option to sign in a different user apart from a different xbox live user. I have created my son a local plex account should I of created him a different type account?
If you could point me in the right direction I would appreciate it :-)
Once you've signed out, you should have no plex account connected to your son's xbox account. When you start the Plex app again, you should see the PIN entry screen.
We use the PIN entry to connect the Plex account to the gamertag. You need to be logged into plex.tv with your son's account. My advice was wrong previously - you need to have a full (but free) account on plex.tv for him, not just a managed account. You can still invite this account into your home.
Once he has a plex.tv account, you should be able to enter the PIN and connect the two.
No problem for the confusion, your help is very much appreciated.
OK, I have created him a plex account , invited him and added him to my home :-) So when I go home tonight do I need to login to his plext.tv account on the xbox one web browser and then open up the plex app to link it to him?
