We're aware of an issue with Facebook purchases for all King Games and our team is on it. 🛠️ Hang tight while we fix things! You can still enjoy the game, and we'll keep you posted once it's solved.
I don't mean just Facebook friends, because my friend doesn't have Facebook but he plays Candy Crush on level 833 but I can not see him on my Rank Board. I checked we are the same version but he use Android I use iOS.
