Task Manager - Reject Reassignment Request Notification?

Summary

Not receiving notification when a reassignment request has been rejected.

Content

I am testing the reassignment request function and when I request a reassignment of task, a notification appears saying that I would be notified if the request has been rejected. However, when the approver of the request rejected the reassignment, I did not received any notifications. I checked my User Preferences settings for notifications and there is not an option for this instance. I also ensured notifications are enabled. I do receive other notifications, such as when a reassignment request has been submitted. Can you please let me know if I am missing something here?
