When iCloud got launched, I of course updated Lion and turned on iCloud. And now my Contacts are all gone.
OS X 10.7.2 with iCloud - no contacts
iOS 5.0 with iCloud - contacts
iCloud.com site - contacts
iCloud storage - 80% space available
All use the same Apple ID.
Here is the investigation I've done so far ...
When I create a new contact on my iPad, it does not make it over to iCloud.com
Appointments made on my iPad make it over to my Mac, appointments made on my Mac make it over to my iPad
When I try to switch on 'Contacts' on my OS X iCloud prefpane, after a while it just unticks the box. All other boxes remain ticked.
When I try to hard-enter a new iCloud account into Address Book, it takes my information and after a while
After inspection of the system.log it seems there are a lot of permission issues and in ~/Library/Application Support/AddressBook I see a lot of Migration*.tbz files which coincide with me ticking the box in the iCloud panel.
