we've been getting some reports of the game only working on wifi (not cellular) connection. in the past, these resolved themselves within a few days so we assumed it was a problem on the cellular carrier side, but just to be sure we want to look into it a bit further.
if you're experiencing this problem, please email us or reply to this thread with the following information:
1. what device and iOS/Android version you have?
2. who is your cellular carrier? (e.g. verizon, at&t, etc)
3. how long have you been experiencing the problem
thanks!
