Unable to access 2015 Nissan #23 GT-R LM NISMO DLC

Hi there, I have the DLC downloaded as it shows up n my games and apps, and through the FM6 marketplace, it states that the item is installed, however I’m unable to access the item, I have tried troubleshooting steps already with Xbox support although the problem still persists

I have now logged on to the game and I can now access the item, so I no longer require any support for this issue
