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.
Does it give you a reason or an error message of some sort? Or does it not even start downloading? I don't know Windows phones very well but I'm sure someone who does will be able to pitch in if I can't find anything.
