title: FCM Notifications not receiving iOS
body: <p>I am using FCM for getting remote push notifications.</p>
  
  <p>So while getting first FCM token from the below callback, I am able to trigger notification and receiving them properly.</p>
  
  <pre><code>func messaging(_ messaging: Messaging, didReceiveRegistrationToken fcmToken: String)
  </code></pre>
  
  <p>After relaunching the app I am getting a new FCM token. No notifications are getting triggered by the new token.</p>
  
  <p>Pre-requisites I'm following according to the documentation:
  <a href="https://firebase.google.com/docs/cloud-messaging/ios/client" rel="nofollow noreferrer">https://firebase.google.com/docs/cloud-messaging/ios/client</a></p>
  
  <p><strong>Using FirebaseMessaging (3.3.0)</strong></p>
