@paulo-pereira The same thing has happened to me. I followed the instructions on the game and I temporarily got a new format of the game. It was awful...full of ads. My game keeps reverting back to the old format which I prefer anyway, but I would like to know how to get my lost players and my history/stats back. I hope that you get a reply as it seems to be affecting many people.

I had the following message on my game and, despite following the instructions and clicking on the facebook button, I've lost half of my games and all of my history, including my stats. I have lost games with players that I've been playing for some time but am unable to contact as they're not on my facebook. How can I get my account reverted back?
