Hello! I have a friend’s account on my console set as my home Xbox and when I got the VIP from him, I am only able to get the cars but not the exclusive rewards and crown in Online. Can someone please help me?
That is how it works - only the owner of the VIP gets those bonuses.
The only option is to buy the vip option via the xbox website on your friends account. Then it will work and the account will get the crown.
