I finished my first ten-hour trial and decided to buy a second ea access membership on my backup account, however when i tried to enter the game it said that i had to wait for the full game to come out

Try setting your backup account as primary and make the Xbox its home Xbox. You may even have to completely remove your primary from the Xbox.

@gbzq You may just need to sign out of your original account, then back in with the 2nd one. There's no harm in doing a quick restart as well.
Let us know how you get on, thank you.
