Hi, I have googled and cannot find an answer to this problem. I have a MacBook Air 2013 running Yosemite. Using the latest version of Numbers if I create a file and save it to icloud on the Mac I cannot open it on my iOS8 devices with Numbers. Both iOS 8 devices, say I need the latest version of Numbers. I click to go to the app store in the iOS8 device and it says I have the latest version and offer to open it. When I open the link to Numbers on iOS8, it will still not read the document. Now if I create the document on either iOS 8 device, I can open it on the Mac version of numbers and the iOS 8 devices. But if i make a single edit on the Mac OS X Numbers the above problem occurs. Thanks!
