When I try to save or load game data, I get the following error:
Error Domain=GKErrorDomain Code=27 "The requested operation could not be completed because you are not signed in to iCloud or have not enabled iCloud Drive"
I'm testing on my iPad2 (iOS 9.2.1) with a developer provisioning profile that has iCloud enabled, and I am signed in to iCloud and have iCloud Drive enabled, so what could possibly cause that error?
