IT KEEPS LOGGING ME OUT OF THE APP!!!

Okay so everytime i try to play, it kicks me out of the app and when i return i have to start from the beginning. I really want to play this game but it keeps getting annoying having to start all over because the app acts dumb, if this does not get fixed ill have no other choice but to delete this app. For now, the game will have 2 stars for me, until i see some changes ill have 5 stars.
