<Google:HTML> You are currently using version 7.6.0 of the SDK. Please consider updating your SDK to the most recent SDK version to get the latest features and bug fixes. The latest SDK can be downloaded from http://goo.gl/iGzfsP. A full list of release notes is available at https://developers.google.com/admob/ios/rel-notes.
Can you check if it is useful to update the sdk on the server ?
It will eventually be updated. Just updating the SDK on the builders is not enough as it requires a change in the library XML. This means that all developers who use this library with the hosted builder will get errors until they update.
