Google has told iOS 9 app developers to disable Apple's enforcement of HTTPS-only connections – or their in-app Google ads won't show up on up-to-date iPhones and iPads.
Apps can be built using the Google Mobile Ads software development kit to show adverts on-screen, and earn developers
cash. By not showing these ads, the programmers lose out on vital revenue.
Apple has added what it calls App Transport Security (ATS) to iOS 9 and OS X 10.11, which ensures software only uses encrypted connections when talking to servers and other systems over the network.
