Hello,
I have followed the article https://developer.android.com/reference/com/google/android/gms/ads/InterstitialAd.html and https://blog.tommyparnell.com/admob-with-xamarin-part-2-interstitialad/ to setup Ads and while I'm using the app using the Test Emulator no ads are loading, basically _testAd.IsLoaded is always false.
See the Notes.txt attached for code.
What am I doing wrong?
