title: Google App Invites Email Not Sent After Play Services Update to 8.3, SMS OK
body: <p>Has anyone else encountered this issue? I upgraded play services to 8.3.0 and android studio preview 2 and since then my app invites won't deliver to email address. Sms works fine. It accepts my requests but nothing happens. </p>
  
  <p>I tried out the sample app and that seems fine but with my app it doesn't work.</p>
  
  <p>I'm testing on a debug key and I deleted and recreated everything got a brand new google-services.json file, nothing works. </p>
  
  <p>I'm suspecting the package name might have some sort of a block from Google side? Can you guys please take a look? </p>
  
  <p>Package name: com.fitzo.android </p>
