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.
There is nothing you can do sorry, the last level that is available on mobiles right now is level 905. There are 920 on Facebook I think. You'll have to wait for the mobile update to be released.
