Upgraded to iOS 8.1.3 -- now will not sync with iTunes
I have just recently upgraded our family's iOS devices--iPad 2(64GB, WiFi/3G), iPad mini (1st gen, 64GB, WiFi), and 2 iPhones (5S, 16GB/64GB)--to 8.1.3, and now, NONE of them will sync properly with iTunes (I have 12.1.0.71 on Windows 7). The sync keeps stopping midway and shows an error message that there is inadequate free space available to perform the sync despite the free space being at least ten times bigger than the amount required (on all devices).
I've tried the "Reset All Settings" option (on the iPad mini), but still no success.
All 4 devices previously shared and used my appleID when they were still in iOS7, and I thought the sync problem was due to the family sharing feature that I had set up after installing iOS 8.1.3 (retained the iPad2 and the 64GB iPhone in my appleID, and setup an appleID for my wife on the 16GB iPhone and the iPad mini). I then tried signing back into iTunes on the iPad mini using my appleID, but the sync still does not go.
Anybody else have the same problem? Have you found a solution?
I'm at wits end...need help fast!
