App Transport Security (ATS) is a privacy feature introduced in iOS 9. It's enabled by default for new applications and enforces secure connections. This may affect your app's integration with the Google Mobile Ads SDK. See the NSAppTransportSecurity documentation for details.
This change affects all iOS 9 devices running apps built with Xcode 7 that don't disable ATS. The following log message appears when a non-ATS-compliant app attempts to serve an ad via HTTP on iOS 9:
> App Transport Security has blocked a cleartext HTTP (http://)
> resource load since it is insecure. Temporary exceptions can be
> configured via your app's Info.plist file.
To ensure your ads are not impacted by ATS, Apple has provided the following
exception that you can add to your app's Info.plist file:
<key>NSAppTransportSecurity</key>
<dict>
<key>NSAllowsArbitraryLoads</key>
<true/>
</dict>
