Issue with leadbolt and admob mediation
<p>I am trying to integrate a custom banner for leadbolt with admob mediation.  I followed the directions on the <a href="https://developers.google.com/academy/apis/ads/mobile-ads-sdk/mediation/custom-events/banners" rel="nofollow">Banners Tutorial</a> and created a CustomAd class, and for parameter I set it to the section ID # from the banner leadbolt dashboard.  I changed the ad unit id in the xml from my publisher ID to the mediation ID.  I set the mediation to 100% in the AdMobCustomEvent, but i'm getting the error:</p>

<pre><code>Invalid unknown request error: Cannot determine request type. Is your ad unit id correct?
</code></pre>

<p>Basically do I need to change any of the code in the CustomAd class or add any extra code to my other classes to get this to work?  </p>
