I have upgraded to Yosemite and iOS8.02 on all my devices, including a MacBook Pro, an iPad2, an iPad Mini, and an iPhone 5c.
I understand that one can use iCloud Drive to share documents produced by any of the iWork apps and also some third-party apps that have been specifically upgraded to use iCloud drive (such as the Readdle suite of apps and Day One).
But, what about the other third-party apps that have not been specifically upgraded? Can files from these apps also be shared on iCloud Drive?
I don't use Pages, Numbers, and Keynote all that much. In fact, I prefer Microsoft Office for Mac. And I have a lot of third-party apps I use a lot more often than any of the former. And, it does not seem to me that all that many of the third-party apps have been specifically prepared to accommodate iCloud drive.
Unless I am missing something, it would seem to me that it is not necessary for me to upgrade to iCloud drive. Do you have any advice or comments about this? Is there anywhere where I might find a list of third-party apps now set up for iCloud Drive?
