InterstitialAd not working with Windows Phone 10 (UWP - Windows 10) - win-universal-app

Question

I cant' get InterstitialAd to work in my UWP app when running on the Windows Phone Emulator (Note that I haven't tried it yet on actual real phone)
It works as expected when I run my UWP app in the Simulator or Local Machine as a Windows Store app.
Any ideas?
Thanks.
UPDATE - 1
Here is the code I use to display the InterstitialAd. In my MainPage.xaml.cs I have the following code:
public sealed partial class MainPage : Page
{
private InterstitialAd interstitialAd;
public MainPage()
{
this.InitializeComponent();
// Instantiate the interstitial video ad
interstitialAd = new InterstitialAd();
// Attach event handlers
interstitialAd.ErrorOccurred += OnAdError;
interstitialAd.AdReady += OnAdReady;
interstitialAd.Cancelled += OnAdCancelled;
interstitialAd.Completed += OnAdCompleted;
}
}
// This is an event handler for the interstitial ad. It is
// triggered when the interstitial ad is ready to play.
private void OnAdReady(object sender, object e)
{
// The ad is ready to show; show it.
interstitialAd.Show();
}
// This is an event handler for the interstitial ad. It is
// triggered when the interstitial ad is cancelled.
private void OnAdCancelled(object sender, object e)
{
}
// This is an event handler for the interstitial ad. It is
// triggered when the interstitial ad has completed playback.
private void OnAdCompleted(object sender, object e)
{
}
// This is an error handler for the interstitial ad.
private void OnAdError(object sender, AdErrorEventArgs e)
{
}
I've literarily taken this code from their UWP Store sample except that instead of launching this from a button, I'm launching it when my page is loaded:
private void Page_Loaded(object sender, RoutedEventArgs e)
{
// Request an ad. When the ad is ready to show,
// the AdReady event will fire.
// The application id and ad unit id are passed in here.
// The application id and ad unit id can be obtained from Dev
// Center.
// See "Monetize with Ads" at https://msdn.microsoft.com/
// en-us/library/windows/apps/mt170658.aspx
#if DEBUG
interstitialAd.RequestAd(AdType.Video,
"d25517cb-12d4-4699-8bdc-52040c712cab", "11389925");
#else
interstitialAd.RequestAd(AdType.Video,
"d25517cb-12d4-4699-8bdc-52040c712cab", "11389925");
#endif
}
I've left both ApplicationId and UnitAdId as the test values for the time being as I haven't released it yet, well, not with ads anyway.
Thanks
UPDATE - 2:
I've added some debugging logs in the various events and this is what I get:
Page_Loaded: 00:00:00.0001590
Page_Loaded - RequestAd: 00:00:00.0091840
OnAdReady - Elasped Time: 00:01:04.6923865
OnAdError: NetworkConnectionFailure : Media timeout occurred
during playback. - Elasped
Time: 00:00:08.1955928
It takes over 1 minute for the OnAdReady to be triggered which is really odd and then I get an OnAdError 8 seconds later so from these logs you would assume that there is a network problem but my data is being loaded correctly which is all pulled from a web service, so there is definitely a connection. Also my AdMediator displays Ads as expected (well, kind of! That's another story!).
I will try to transfer it directly to my phone tomorrow and see if it makes any differences and I plug in my laptop to an Ethernet port instead of using the wireless but my wireless is pretty decent, so I'm not sure why I'm getting network connectivity errors.

Answer 1

The above code is correct and does actually work with UWP on Windows Phone but it doesn't work great in the emulator as:
it intermittently generates network connectivity errors when they are none.
it can take over a minute to display the advert but it eventually will.
I've just uploaded my app to the store and downloaded it to my phone and it works as expected. It displays the advert immediately or within a couple of seconds or so.
I would recommend you do not waste too much time trying it via the phone emulator as it appears to be the main problem. Implement your code and then test it directly on your device or download it from the store assuming you haven't released your app yet.
UPDATE:
I just thought I'd update my answer as I was just reading about the do's and dont's with interstitial adverts from UI and User Experience Guidelines and the way I'm actually doing it, is one of points in the "avoid" list.
It recommends that you fetch the advert 30-60 seconds ahead of time and you don't display it when the app starts, which is what I'm doing, so I guess I will change the logic in that regards.
