Local Notification don't play sound or vibrate in background on IOS

I am using Firebase push notifications and they are working fine i.e with sound and vibration but when the app is in background mode then the notification is being received without vibration and sound. On Android, only sound is playing in all modes without vibration. My code is:

messaging().onMessage(async remoteMessage => {
      PushNotification.localNotification({
        vibrate: true,
        vibration: 300,
        playSound: true,
        soundName: 'default',
        importance:'high',
        invokeApp:true,
        allowWhileIdle: true,
        priority:'high',
        visibility:'public',
        /* Android Only Properties */
        title:remoteMessage.notification.title, // (optional)
        message:remoteMessage.notification.body, // (required)
        invokeApp: true,
      });
      // sendMessage(remoteMessage.notification.body, remoteMessage.notification.title)
    // Alert.alert('A new FCM message arrived!', JSON.stringify(remoteMessage));
})

You define it

[jgalianoz]

push_service.notify_multiple_devices(
 registration_ids=[registration_id_ios],
 message_body=message_body_ios,
 content_available=True,
  data_message={ },
  sound="default"
)

@faizanbuggy I resolved this by adding a sound="default" param in my service that sends the push notifications in the backend. Maybe you can try this.
