Hello there,
Today I’m experiencing this issue, which makes every dlc content from my car pass “unavailable”:
When I try to access any “car pass” or “dlc” car, it basically says I didn’t bought the content from the store, and when it tries to redirect me to the store it says “unable to reach the store - try again later”.
I have the ultimate edition, with everything installed (also tried to reinstall the car pass, it returns me errors).
Everything else is working normally, I’m even able to play online.
