Update to iOS 10 or 11
I tried to download an app from App Store but got a message that I need iOS 10.
Howeaver my iPad has iOS 9.3.5 and it states it's the latest software.
Catch 22 situation. How do I get 10 or indeed 11 as the system won't let me do any iOS update given its indicating I have latest version
iMac, OS X Yosemite (10.10)
