onNotificationOpened works in Android emulator but not in actual device

I am using firebase notification module in my react-native application. It works perfectly in emulator but when I install the app in mobile, onNotificationOpened event listener never gets called when I open the notification. what am i missing ?

Environment

• Development Operating System: Windows

Build Tools:

• React Native version: 0.60.5
• React Native Firebase Version: 5.5.6
• Firebase Module: notifications

Code Snippet:

  this.notificationOpenedListener = firebase.notifications().onNotificationOpened((notificationOpen) => {
      Linking.openURL('https://www.google.com/');
  });

  /*
  * If your app is closed, you can check if it was opened by a notification being clicked / tapped / opened as follows:
  * */
  const notificationOpen = await firebase.notifications().getInitialNotification();
  if (notificationOpen) {
      Linking.openURL('https://www.google.com/');
  }
