My mobile devices are still on IOS7 and using iCloud. When I upgrade my mac to Yosemite I loose the ability to sync between IOS7 devices and my iCloud (drive) on the Mac. Is there a way to keep the ability to sync numbers and pages documents between Yosemite and IOS7 devices? I am afraid that the only solution is to upgrade to IOS8 on the mobile devices or go back to Mavericks on the mac (as I did). Suggestions are welcome.
