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 have this problem too. I contacted King and sent a screenshot, they said try a different browser, use Chrome, etc... every thing is good on my end, it's not my computer! They changed the settings bar and now it blocks the game all the time!
