title: Firebase Audience Targeting on Count Operators
body: <p>I use Firebase Analytics &amp; Audiences for event tracking &amp; push notification campaigns. I want to target my app's users that did not have an <code>in_app_purchase</code> across their entire lifetime. </p>
  
  <p>I created the following tests in the Firebase Analytics Audiences dashboard, but could unfortunately not save &amp; create the audiences:</p>
  
  <ul>
  <li><p>Test 2 below does not work with <code>in_app_purchase Count &lt; 1</code>. </p>
  
  <p><a href="https://i.stack.imgur.com/e6sN3.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/e6sN3.png" alt="screenshot"></a></p></li>
  <li><p>Test 3 does not work with <code>in_app_purchase Count = 0</code>.</p>
  
  <p><a href="https://i.stack.imgur.com/9Tmnt.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/9Tmnt.png" alt="screenshot"></a></p></li>
  </ul>
  
  <p>I assume I am not the only one that want to grow their buyer segment. So, I am curious how one would be able to create this audience in Firebase (and target them thereafter with a push notification)?</p>
