I won the jackpot this morning. But it wouldn't let me claim it. I kept pushing on the button, but nothing happened. I finally had to just close the screen and of course it was gone when I re-opened the game.
I have sent you a private message, so that we can check your player account. Please click on the envelope icon on the top right corner of the screen and kindly get back to me with the details in order to solve the issue.
