iCloud syncing not working with OSX Mavericks and iOS 8

Hi,

Starting with iOS 8, Documents are now synced via “iCloud Drive”. This is not compatible with the previous “iCloud sync”. Please see here:

It’s about iWork but the same applies for all other apps that use iCloud Documents to sync.

iCloud sync with iOS 8 will only work with OS X Yosemite, on which you have to switch to iCloud Drive as well.

By the way, you should have gotten a message regarding this when you chose to switch to iCloud Drive.
