Help can't update to iOS 10.3.3
I have an iPad Air 2 and when I check for update it says I can update to iOS 10.3.3 but when I down load the update it won't install it says cannot verify update no internet connection which is wrong. I've tried this on multiple wifi hotspots including my personal wifi and deleting and redownloading the update on each and its the same thing. I've also tried to update with iTunes on my computer but when I open iTunes and select my devise and click check for update it says I'm up to date with iOS 10.3.3 and when I look under about on my iPad it also says I have 10.3.3 so how is there an update to a softwear I already have. Some one help please I just want to update so I can get iOS 11.
iPad Air Wi-Fi, iOS 11.0.3
