Heyzap Ads on Phonegap. Don't fetch video with tag 'default'

I write code below:

document.addEventListener('deviceready', function() {

    HeyzapAds.start("HeyzapKey").then(function() {
        // Native call successful.

        // Start fetching ads
        HeyzapAds.InterstitialAd.show().then(function() {


        }, function(error) {
            // Handle Error
        });

    return HeyzapAds.showMediationTestSuite();

    }, function(error) {

        // Handle Error
    });

}, false);

Then see next page: showMediationTestSuite
Then go to Heyzap and have problem: didFailToReceiveAd with tag 'default'

Problem in my code or in Heyzap account preferences?

it looks like heyzap isn't aware of your game com.luckycatstudios.guessywords. Use the heyzap dashboard to claim your game, and you should be able to see ads.

You can use this link to claim your game: https://developers.heyzap.com/dashboard/games/add_game

If you still have trouble, send a message to support@heyzap.com ideally with a copy of your app we can use to debug.

Thanks!
