I had the same issue, resolved it by adding the code below after receiving the fcm token,

FCM.setBadgeNumber(0);

Above is for android for iOS you need to turn on background notifications in Xcode. In Xcode select your project and open capabilities and see if background modes in on. Refer to the screenshot

Here is the snippet of the code i used

export const MyNotificationReceiver = props => {
  FCM.getInitialNotification().then(notif => {
  });

  FCM.setBadgeNumber(0); //Add this for background notification

  this.notificationListener = FCM.on(FCMEvent.Notification, async notif => {
    var notification_messgae = "";
    try {
      notification_messgae = notif.default;
    } catch (error) {
      notification_messgae = JSON.stringify(notif);
    }
    if (osDetection) {
      switch (notif._notificationType) {
        case NotificationType.Remote:
          notif.finish(RemoteNotificationResult.NewData) //other types available: RemoteNotificationResult.NewData, RemoteNotificationResult.ResultFailed
          break;
        case NotificationType.NotificationResponse:
          notif.finish();
          break;
        case NotificationType.WillPresent:
          notif.finish(WillPresentNotificationResult.All) //other types available: WillPresentNotificationResult.None
          break;
      }
    }
    if (!osDetection()) {
      if(notif.default)
      {
        FCM.presentLocalNotification({
          body: notif.default,
          priority: "high",
          show_in_foreground: true,
          large_icon: "noti_icon",                           // Android only
          icon: "noti_icon",                                // as FCM payload, you can relace this with custom icon you put in mipmap
          android_actions: JSON.stringify([{
            id: "view",
            title: 'view'
          }, {
            id: "dismiss",
            title: 'dismiss'
          }]) // for android, take syntax similar to ios's. only buttons are supported
        });
       }

    }
  });
};
