I have 26 students in one class. When they submit their assignment, usually I am able to see it on speedgrader and grade it. But I have noticed that out of 26 students, only 4 students' work is showing up. Also, I just gave them a quiz. Again, only 4 students log is showing up, however, I am able to download all the students' results.
How can I fix it so I can see all students' work on speedgrader and view their activity log.
