I got delivery of an iPad Air yesterday.I set it up manually. It called for creating a 6 digit passcode, which I did. This morning I rebooted it while trying the new shutdown procedure. When it restarted it presented a passcode screen to initiate touch ID. But the passcode screen was for only 4 digits, not 6. So there’s no way to input my passcode, hence I now have a brick. When I finally got through to Apple support the guy said, as expected, that must be an iPad OS problem. We tried a couple of work-arounds but no luck. The only thing left to do is connect the iPad to my PC and do a full reset. But there’s another problem. The only port on the iPad Air is a USB-C. My PC (and I bet most computers) is USB-A. So I had to go to BestBuy and buy a third party cable with USB-A on one end and USB-C on the other. Tomorrow I’ll try to get help with the reset. Not a good beginning. I do not recommend buying an iPad Air at this time.
