Firebase App Invite stop working with Dexguard
<p>My app works fine. But in preparation to go to production, I applied Dexguard. With Dexguard Firebase AppInvite no longer works. When I send an invite, I get by the snackbar</p>

<blockquote>
  <p>Message failed to send!</p>
</blockquote>

<p>How do I make Firebase App Invite work with Dexguard? Btw, I have no problem with Firebase Cloud Messaging.</p>

<p>I am using</p>

<pre><code> compile "com.google.firebase:firebase-invites:9.0.0"
</code></pre>

<p>and</p>

<pre><code> classpath 'com.google.gms:google-services:3.0.0'
</code></pre>
