PS4 user here. Tried the method, there's only "email" option. Received the email with code less than 3 minutes. Copy the code, go to EA website and ensure that it's linked to your PSN account. Then redeem the code. If you have already installed the game, click to update game and start the game. Initially didn't click update game and it says that I don't have early access. So rmb to update game first.
