Since a few weeks I only see one iCloud calendar on my iPhone. I checked: all my devices use the same ...@mac.com address, and in iCloud.com I can see all (8) my calendars. However on my iPhone 4 running iOS 7.1.1 (at least since 7.1) I only see one calendar from iCloud. I tried a few things without success (each time I got a different calendar on my iPhone, but always only one): disabling iCloud calendar, reboot, enabling iCloud calendar, reboot removing iCloud account, reboot, adding iCloud account, reboot factory-resetting iPhone and restoring from iCloud updating to iOS 7.1.1 I also noticed that when I few my calendars on iOS (where I only see on), when touching the "i" Button the Calendar App crashes. Any tips what I can do to get all my calendars on my iPhone?
