title: Firebase Cloud Messaging Notifications for iOS not showing opened and analytics
body: <p>I'am using FCM to send notifications to iOS apps. The notifications are received on the device well, but I can not get the "Opened" or "Conversion " rate in the Notification console GUI. It always shows "0 opened" and "0 Conversion" for almost 200 0000 notifications sent.</p>
  
  <p>I double checked all the implementation but I can't get it working.</p>
  
  <p>I have <code>FirebaseAppDelegateProxyEnabled</code> set to <code>YES</code> in plist. I implemented all the methods listed on Firebase guides and docs.</p>
  
  <p>I don't have any notification related events showing in the Firebase analytics pane either.</p>
