I have been using the attendance function in my class all semester, and suddenly Attendance is missing from my navigation. Not greyed out - GONE. It's not in the left-nav, and in settings, it does not appear in the available items to add. I have the student and teacher apps, and at first, I could still see it in the student app, but not the teacher app or on my laptop. Now it's gone everywhere. I can still see it in all three places in my other course. Has anyone else had this happen? My college's IT dept is mystified, but not able to help... Thanks!
