Can't delete iCloud backup, storage full
After upgrading my iPhone 6 Plus to IOS 9, my iCloud storage shows 5GB of my 25GB available. It shows an iPad Air (not yet updated to iOS9) backup of 516MB, and an iPhone backup of 0 KB, which I cannot delete (This backup cannot be deleted at this time). Documents and Data only 6.9MB, but only 5 GB available, and not enough room to continue to back up the iPhone. The 19GB iPhone backup appears to have been corrupted and cannot be deleted or updated by the phone. Looks like lots of folks are having similar issues. Any solutions?
Apple has been spending lots of energy creating new, exciting products but has been lax on supporting the back end, which is just as important. iCloud for Windows still not updated for Windows 10, and iTunes has issues with Windows 10, not resolved in iTunes 12.3. Come on, Apple!
