It also didn't work on my iPad Pro 9.7. Well, it started to install, then stalled.
It installed on the second try, through iTunes instead of OTA, but was so broken that Support had me enter recovery mode and restore...which also failed. So, a couple more "regular" restores, and it sort of resembled an iPad, but most of my apps and photos were missing the first time; all but two apps showed up overnight. Nothing involving iCloud, which is a lot more stuff than you think, was accessible. I could not even sign out of iCloud from the iPad--I had to kill it off from the Apple ID web site, on my iMac. For some reason, the 600+ missing photos started reappearing later this morning.
iCloud started working again after resetting wifi, i.e., losing all my passwords, but one app would not reinstall from iTunes even though it appeared in the app list. Not a big deal to re download the app, but several years of data are MIA. In the past two days, I've spent about 6 hours on the phone with Apple, including hold time, got cut off once, had one message not returned, and got patronized by five semi-knowledgeable support agents. Add another few hours trying to fix lost settings, resulting in an RSI, and my day of jumping through flaming hoops has not gone well.
My irreplaceable data is still missing; it has to be somewhere in Time Machine, but so far no one knows where it is or how to retrieve it. Some techie who might know is supposed to tell a support agent who is supposed to call me tomorrow. I have little faith at this point that I'll ever get the data back. I foolishly trusted iTunes to back it up.
Friends, if you've not yet done the 10.3 update, this is one to consider passing up.
