Game keeps freezing up and lagging often at critical moment's in the game. I enjoy playing this game but there are some changes going on i.e I get ads but after Every round? It changed from maybe an ad every 2/3 rounds . Now you are forced to watch at least 2 ads and often will repeat the same 2/3 ads back to back making it harder to return to the game. This needs to be addressed if you every expect to get a higher rateing!
