To all iPhone users:
I talked to Apple’s developer support. They confirmed the issue with our update 1.15.0 not showing up in the AppStore and will investigate. They could not give me any time estimate for finding a resolution though. We are sorry about this inconvenience, and we hope you can play on the servers we have not upgraded yet in the meanwhile.
Update: version 1.15.0 is finally available in the AppStore now.
