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 don't know what plugins and extensions are let alone how to disable them. I've tried closing all programs in the background, but still have the problem. I just tried the link you suggested and no luck-same issue.
