title: Firebase Android client loses authorization
body: <p>I am developing and Android base Firebase application using basic email/password authorization.  On two of my phones it works fine (Nexus 5 and 5x).  On my Nexus 6 the the application authorizes successfully and downloads a large query, but then about 1 second the user becomes unauthorized (I'm monitoring via an AuthStateListener).   All the devices are using the same credentials.  The two Nexus 5's successfully operate at the same time.   Logging both of them out doesn't help the third phone.</p>
  
  <p>Any ideas?</p>
