Thank you for posting your concern here. I understand how frustrating it may be to be unable to access your pre-order DLC once you upgraded consoles. We are aware that players are not able to access their pre-order items once upgrading at the moment and we are currently looking into it. We will update the community once we get more information on what's going on with your DLC, and thank you again for your patience!
