Login issues after buying game after trial

hi I’m new here,

I seem to be having issues trying to get on to fifa on Xbox. I used the 10hr trial then bought the game. Now when I load it up the message says that the trial has ended and won’t let me past main screen. I have uninstalled and reinstalled full game but did not work my only work around has been turn the internet off then get the game to the main menu, then turn the internet back on that seems to bypass it. Surely there is another way so I don’t have to keep doing that.

any ideas?

thanks in advance
