I bought the season pass back in september. i have the 1000 club and rally dlc, but i don’t have access to the car packs.
i contacted xbox support, in the end they said it’s a game bug and i should ask in this forum.
did anyone have more luck?
No. You can try to copy the free cars from a friend Xbox and your Season Pass will unlock them.
It’s actually the same solution people used one month before delisting. As in-game-marketplace wasn’t working everyone downloaded the free content from the dashboard/website. The difference for you will be just the means to obtain the content.
