EA account not fully linking with xbox account

So I bought the xbox game pass and was trying to get titanfall 2 so I made an EA account to get it (the game should be free with the gamepass) But after linking my xbox and EA accounts it says I need to pay money for it even though it should be included in the gamepass. I used different emails for my xbox account and the EA account so that might be the problem. If so how would I fix it?
