title: Firebase Auth Not working & Completely Unreliable for the past few days
body: <p>The following was working perfectly for months.
  The code has recently started to break for the past few days without any changes on app side. Most probably Firebase broke something on their end and already logged in users have started to throw the following errors.</p>
  
  <p>Firebase support is completely unresponsive, so asking it here.
  Anybody still stuck on Firebase Please Help.</p>
  
  <p><strong>Code Used:</strong> </p>
  
  <pre><code>FirebaseUser user = FirebaseAuth.getInstance().getCurrentUser();
          if(user == null &amp;&amp; !OAuth2Utilities.isBlocked(context)){               
              OAuth2Utilities.initAnonymousFirebaseAccount(context.getApplicationContext());
              return null;
          }
          String userId = user.getUid();
          Task&lt;GetTokenResult&gt; z1 = user.getToken(false);//true means it force refreshes the token, false means will update only if expired-- token by default expires in an hour
          try {
              Tasks.await(z1);
          } catch (Exception e) {
              e.printStackTrace();
          }
          final String z2 = z1.getResult().getToken();
  </code></pre>
