Amazon mobile ads interstitial not loading

Question

I am using Amazon Mobile Ads interstitial. I do have AdRegistration.enableTesting(true); and this.interstitialAd.loadAd();. But when App should show Interstitial Ad, in LogCat i get:

07-21 11:21:51.653: W/AmazonMobileAds InterstitialAd(13446): The interstitial ad cannot be shown because it has not loaded successfully. Please call loadAd(AdTargetingOptions) to load an ad first.

P.S. When I made it it was working. Two days later when I started the app again, it started showing this warrning.

Answer 1

Read the docs, they tell you how to add

loadAd(AdTargetingOptions)

and you can set the geolocaction tracker (optional)
