UnityEngine.iOS.NotificationServices.CancelLocalNotification does not remove notifications

Question

I am currently building a class to handle notifications for my Unity3D game for iOS. But when I am using UnityEngine.iOS.NotificationServices.CancelLocalNotification (nt); nothing happens to the scheduled notification.

Can someone help with pointers how to makes this work?

As an alternative I can use UnityEngine.iOS.NotificationServices.CancelAllLocalNotifications but that will be much less elegant.

I am using Unity 2017.2.0f3 and iOS 11.2.1 on a iphone 6S.

public void UpdateMorningNotifications()
{

    // Get all current scheduled morning notifications in a list. if they are type morning. erase them.
    UnityEngine.iOS.LocalNotification[] scheduledNotifications = UnityEngine.iOS.NotificationServices.scheduledLocalNotifications;

    Debug.Log ("NotificationScheduler/UpdateMorningNotifications - number of scheduledNotifications = " + scheduledNotifications.Length);

    foreach (UnityEngine.iOS.LocalNotification nt in scheduledNotifications) 
    {

        Debug.Log ("NotificationScheduler/UpdateMorningNotifications - clearing notification, type is " + nt.userInfo["type"] );
        if (nt.userInfo ["type"] == "morning") 
        {
            Debug.Log ("Its a morning nt, lets get rid of it!");
            UnityEngine.iOS.NotificationServices.CancelLocalNotification (nt);
            Debug.Log ("NotificationScheduler/UpdateMorningNotifications - clearing notification: " + nt.alertBody);
        }

    }


    // building, and adding notifications to notificationservices.
    DateTime fireDate = DateTime.Today;

    int summedInterval = 0;
    // fill up the morning timings list.
    foreach (int interval in MorningNotificationDayInterVals) 
    {   
        // adding new interval to firedate
        summedInterval = summedInterval + interval;
        fireDate = fireDate.AddDays (summedInterval);


        // if weekend fire at 10AM else 8 AM
        if (fireDate.DayOfWeek.ToString() == "Saturday" || fireDate.DayOfWeek.ToString() == "Sunday") {
            fireDate.AddHours (10);
        } else {
            fireDate.AddHours(8);
        }

        //generate notification with random title and the timing and add it to the batch.
        int morningTitleIndex = UnityEngine.Random.Range(0,morningTitles.Length);

        // generating a new notification.
        notification = GenerateNotification (morningTitles[morningTitleIndex], fireDate, "morning");

        // adding the notification to the batch.
        notificationBatch.Add (notification);
        Debug.Log("NotificationScheduler/UpdateMorningNotifications: Length of notificationBatch = " + notificationBatch.Count);
    }

    // Adding notifications to notificationsservices
    AddNotificationBatchToNotificationServices (notificationBatch);


}

Solved. There was a bug in. if (nt.userInfo ["type"] == "morning") should be if (nt.userInfo ["type"].ToString() == "morning")
