We're aware of an issue with Facebook purchases for all King Games and our team is on it. ๐ ๏ธ Hang tight while we fix things! You can still enjoy the game, and we'll keep you posted once it's solved.
@kiara_wael every member of team Friends must play in CCFS as many levels possible for challenge #4 in a period of 1 week. The week starts when you post your map and you posted your map. So you have 1 week to complete challenge #4.
