same problem, We use only computer and for son I bought separated GP Ultimate, but on his account we can not play EA games.
In EA app on his (child) account there is no any additional option etc,
There is also imposible to unlink this account with XBOX app. ----- because EA APP is just empty. At the same time we can not login to his EA account via WWW because there is need email adrdress. His EA child account was made via XBOX app and in this situation we have only EA login, not email which is necessary to login EA account via WWW.
I just want to add to this, I Actually contacted EA support, and guess what, THEY WILL NOT TELL YOU THAT YOU CANNOT USE A CHILDS ACCOUNT OT PLAY GAMES, they will try to * anyhting and try to troubleshoot blah blah blah, BUT THEY KNOW, they rather waste out time then straight out say, hey if you are not 14 or whatever your account is USLESS! but we will take your money while you try to troubleshoot this issue. It is 100% a SCAM.
