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'm having this problem too, restarted and even uninstalled, reinstalled the game which emptied a lot of my booster inventory and i had just purchased the special running today so I'm very frustrated. I have a day of boosters automatically and i cant deactivate.
