title: Firebase Cloud Messaging: Invalid APNs certificates
body: <p>I am not able to send push message to iOS device from FCM console. I receive error message "Check APNs certificates in settings". My configuration is the same as in FCM guide:</p>
  
  <ol>
  <li>I generated Auth Key in Apple Developer Account.</li>
  <li>I uploaded auth key in Firebase project, put Key Id and prefix (Team Id).</li>
  <li>I added FCM SDK to my iOS project (added Google-service.plist as well).</li>
  <li>I saved registration token in Firebase Database.</li>
  <li>Finally, I can send a message to all devices with my App ID (but cannot receive this message, I do not know why), but I cannot send a message to selected device with token.</li>
  </ol>
  
  <p>Any ideas? </p>
