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 had a similar problem a while back (the issue resolved itself), however I did notice that if I played the game in my mobile the tickets and gifts from my friends were there. Are you able to test it in a mobile/tablet in the meantime until the problem is fixed?
