I have an assignment that students need to turn in. All of my students in this class have the reassign button show up in the speedgrader. BUT, I have one student in that class that the button does not show in the speedgrader. Anyone know what is going on? The assignment is set up just like every other one. They have another 3 attempts to turn it in, and I have graded it and given feedback. But the button is not even there, much less clickable.
