Just to follow up on what Kristin said; it's actually a grade notification since Roll Call Attendance is linked to the gradebook. In addition to a notification they also will see a little dot next to Grades each time letting them know there is a new grade. One thing I've noticed is that there tends to be a delay for grade notifications of about 20 minutes. I don't think I've seen it documented, but in my own experimenting this is the case. I only point it out here because of your comment about students showing up 20-30 minutes later. That matches pretty close to my observed delay of grade notifications.
