** Also a suggestion from a fellow player... If you describe more about the issue it will be very useful for the King Team to look into it & help you with any necessary suggestions. For example, which platform you are having issue -- Mobile phone / Ipad / PC; If PC, Chrome / Game Room, etc; When did the problem start OR you could not open the App at all, etc., details will really help!
