title: Firebase Analytics not showing utm* parameters
body: <p>I've set up Firebase Analytics and am successfully using dynamic deeplinks, however when I look at the attribution reports, there is no data for utm_source, utm_medium etc.</p>
  
  <p>Here is an example dynamic link:</p>
  
  <pre><code>https://[redacted app_code].app.goo.gl/?ibi=com.[redacted hostname].FirebaseTest&amp;ifl=http://www.[redacted hostname].com/apps&amp;ad=1&amp;utm_source=testsource&amp;utm_medium=testmedium&amp;utm_campaign=testcampaign&amp;link=http%3A%2F%2Fwww.[redacted hostname].com%2Fdeep%2Flink
  </code></pre>
  
  <p>This is the partial log with FIRAnalyticsDebugEnabled:</p>

  </code></pre>
  
  <p>I do note the <code>Deep Link does not contain valid required params</code> part... What "required params"?</p>
  
  <p>Is there something else that has to be done to see the passed in utm* data in the Attribution tab in Firebase Analytics?</p>
