I just bought that too using a coupon for the base game and then the season pass. Pretty much the Gold Edition for $11, i don't see that price happening elsewhere anytime soon so thought why not.So I just got AC Origins with the 10$ from free GTA and it literally wont let install it because I have never linked my UBI account. Also wont let me link my UBI account.
I hope they fix that linking issue ASAP because I don't believe i've ever done it on my account.
