Game Code is invalid?

So today was Gifted for xmas a Digital Standard Endwalker Code through Amazon, and when I attempted to redeem the Game Code I've gotten "This code is Invalid", I'm made to type the code exactly as given to me by Amazon, and still same issue. The purchase was made today, so i don't know how there would be an issue.

Anyone else having similar issues, and if so how do I try to address this?
