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 am having the same problem on my iPad. I do have the latest version downloaded. Getting a bit old because I have to completely close out the game and reopen if I want to play. Hope it gets fixed soon!
