Notifications Framework not working when grade is posted.

We've been trying to get the Notifications Framework working in Campus Solutions, so that we can have emails automatically sent to students when one of their grades is posted.

Our Notification Consumer, Notification Template, and Generic Template all appear to be set up correctly based on the documentation. Our test student has the proper notification preferences selected. Also, we've checked the settings for the relevant Service Operations and were unable to find any problems.

At this point, we're not sure what is preventing the notifications from being sent.

Has anyone else encountered similar issues with the Notification Framework not working for grade added emails? If so, what did you have to set up to get it to work?
