My iPhone and iPad are both new, purchased together, same iOS. Runs great on iPhone. iPad crashes, freezes, runs slowly, and can rarely connect to Facebook or Gamecenter. All of my other Zynga games run smoothly on my iPad. It is very frustrating. Zynga has poor customer service, I recently had 7 back and forth emails about Draw Something, and they were useless, so I am not bothering to contact them again. I do enjoy the game, I spend $5 here and there, but why shouldnt I? Zynga is a business, so whiners about its too hard to get keys, it is worth it to occasionally buy them, as it makes the game much more enjoyable! And join a coop, its a necessity. Just fix it on iPad!~Thank you
