Hi, I just purchased Lego Marvel Super Heroes here in the UK and I received a code to download the Super Pack in the box. I redeemed the code on the Xbox.com site and now the Add-on won't show up anywhere on my Xbox One. I've looked in 'See all add-ons' and the Super Pack is also on the Xbox Games Store but I there is no 'Install' button to download this.
How can I get the code?!
