title: AdColony interstitial ads not showing(Unity Android)
body: <p>So I've faced with a problem when trying to show interstitial ads on my device.</p>
  <p>Requesting interstitial ads always return a success message, but when I try to call show function, nothing happens.</p>
  <p>It only happens with interstitial ads, because banner ads are working and showing on device.</p>
  <p>Also, AdColony dashboard receives new requests, but still showing functions doesn't work:

  <p>I've tried using both live and test ads.</p>
  <p>I'm using:<br />
  Unity 2020.1.4f1<br />
  External Dependency Manager 1.2.156<br />
  AdColony 4.3.1</p>
  <p><strong>This is part of the code I'm trying to run:</strong></p>
  <pre class="lang-cs prettyprint-override"><code>AdColony.InterstitialAd _ad = null;
  
  // Start is called before the first frame update
  void Start()
  {
      string[] zoneIds = new string[] { &quot;myZoneID&quot; };
      AdColony.Ads.Configure(&quot;myAppID&quot;, null, zoneIds);        
  
      AdColony.Ads.OnRequestInterstitial += (AdColony.InterstitialAd ad) =&gt; {
          _ad = ad;
      };
  
      AdColony.Ads.OnExpiring += (AdColony.InterstitialAd ad) =&gt; {
          AdColony.Ads.RequestInterstitialAd(&quot;myZoneID&quot;, null);
      };
  }
  
  public void Request()
  {
      AdColony.Ads.RequestInterstitialAd(&quot;myZoneID&quot;, null);
  }
  
  public void Show()
  {
      if (_ad != null) {
          AdColony.Ads.ShowAd(_ad);
      }
      else
      {
          Debug.Log(&quot;null&quot;);
      }
  }
  </code></pre>
  <p>Is there any way to fix this problem?</p>
