Hi, there is a bug in the iOS version of shift 1 and 2: you cannot play offline without having a pop up message that says "Achievement Reload Failed! Reason: The operation couldn't be completed. (NSURLErrorDomain error -1009.)"
If I press "OK", the message disappears and reappears immediately.
I'm not the only one to have that issue, so it doesn't come from a bug on my device.
Can you work on an update? I paid for these games and they doesn't work properly
