title: React Native Android remote push notifications not showing up
body: <p>I am using the <code>react-native-push-notification</code> package and PubNub push notifications to handle the remote notifications. This all works on iOS just fine and I'm getting the notification data coming in from the <code>onNotification</code> method on android but there is no actual notification popping up on the screen as I would expect. Am I missing a configuration on the FCM side maybe or a specific permission check I need to ask for to make sure remote notifications can be shown on android devices?</p>
  
  <p>I've followed the manual steps on the <code>react-native-push-notification</code> package to a T and triple checked I didn't miss something</p>
