i put a $100 in to try it out and get their bonus, just having some fun. however, when i sign in to mobile it sometimes kicks me out and asks me to reenter my username and password over again. when i do it from my laptop, i have problems with college games. the screen freezes and i can't type my bets into the boxes next to the teams. anyone else getting this? i am disappointed with the quality of the book so far just based on these issues, seems like a 15 yr old designed it with these flaws.
