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.
What are you playing on? Facebook or a mobile/tablet? If you're playing on a mobile then you just need to update the game via your app store. If you're playing on Facebook the levels will automatically be there.
