I GOT MY CODE!!

Did they email you through the email you signed up for the playtest with, or the one thats assosiated with your EA login? I'm a bit confused cause I got in through my current email, then did the steps of signing in with my Xbox login, which then linked to an old EA account with an email that AOL deleted years ago. So now my login says I'm in a playtest, but idk if they're now sending the invites to that AOL, or the email I originally signed up with? 

But I think it was this step that basically merged my old account with the one I was using before? 

Like I do not have access to the email for this account I'm using now, the only way I'm using this is with the Xbox sign in, which I never used to sign up for the playtest. So... not sure why this account has access to this forum and not my other one?
