react-native-firebase: onNotificationOpenedApp and getInitialNotification not working on iOS

I'm using Cloud Messaging from react-native-firebase 7.0.1.

I do not want to store iOS device tokens in firebase, so I'm using getAPNSToken() method and then storing it on my backend.

I'm able to send notification on a device and after pressing it, the application opens.

But when I'm trying to get message from getInitialNotification() or onNotificationOpenedApp() it always returns null/undefined.

It works every time on Android.

PushHandler.js

import React from 'react';
import messaging from '@react-native-firebase/messaging';

export default class PushHandler extends React.Component {
  constructor(props) {
    super(props);
    this.messageApp = messaging();
  }

  componentDidMount() {
    this.messageApp.onNotificationOpenedApp(remoteMessage => {
      if (remoteMessage) { // <- always null on iOS
        // handle notification
      }
    });

    this.messageApp.getInitialNotification().then(initialMessage => {
      if (initialMessage) { // <- always undefined on iOS
        // handle notification
      }
    });
  }
  render() {
    return null;
  }
}
