title: AdMob interstitial Ad is shown but can't click on it
body: <p>I've got an app that displays an Interstitial Ad when certain activity is closed. I use a different activity to show the Ad. So far it shows the Ad correctly but nothing happens when I click on the Ad. I've tested it on many devices and beta testers report the same behavior. There are no errors in the logs. It's the same if I use debug build or signed APK that is uploaded to the play store (it's published in alpha state if it matters). I use the latest Play Store Services SDK.</p>
  
  <p>What could be the reason for this?</p>
  
  <p>My activity that shows the Ad (I use the correct unit id in the actual code)</p>

  <p>The layout (I've tried to not use any layouts with same results).</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
      android:layout_width="match_parent"
      android:layout_height="match_parent" &gt;
  
      &lt;ProgressBar
          android:id="@+id/prgrssBrAd"
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          android:layout_centerInParent="true" /&gt;
  
  &lt;/RelativeLayout&gt;
  </code></pre>
  
  <p>I would appreciate any help you can provide.</p>
  
  <p><strong>UPDATE</strong></p>
  
  <p>It seems that I managed to find the problem. It was related to the AndroidManifest configuration:
  Old one, Ads are not clickable:</p>
  
  <pre><code>&lt;activity
      android:name="com.google.android.gms.ads.AdActivity"
      android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize"
      android:launchMode="singleInstance" /&gt;
  </code></pre>
  
  <p>Good one, works fine:</p>
  
  <pre><code>&lt;activity
      android:name="com.google.android.gms.ads.AdActivity"
      android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize" /&gt;
  </code></pre>
  
  <p>Sorry for the confusion, I cant recall when I did that change.</p>
