Xamarin Firebase Authentication
<p>I am testing firebase authentication (and messaging). I am using:</p>

<p>Xamarin Firebase 32.4.0-beta2
Xamarin GooglePlayServices 32.4.0-beta2</p>

<p>When I call this:</p>

<pre><code>FirebaseAuth auth = FirebaseAuth.GetInstance(app);
</code></pre>

<p>I get this error:</p>

<blockquote>
  <p>Java.Lang.NoClassDefFoundError:
  com.google.android.gms.internal.zzafi$zza</p>
</blockquote>

<p>Can anyone point me in the right direction?
Thanks!</p>
