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.
Check out the help video from King and follow the steps they provide. I have this saved in my bookmarks and it's helped me in the past. Hopefully this will get you back on track:
