As of the morning of Sept. 16 the game won't let me login unless I update the app on the iOS store. There is no update as that comes out on the 18th. Even clicking on the open button within the App Store just loops you back.
We're just in the process of updating the game and the servers, I'll let you know as soon as that's done Don't worry though you're not going to have to wait until the 18th!
