My course is set up so there are three sections that I cross-listed into one course. I used Flipgrid as an external tool to create an assignment for students. I created three separate assignments, one for each section of students in the course. When I try to use speedgrader to grade the videos, I can only see students listed for one of the assignments. In the other two assignments, there are no students listed at all. When I look at the grid, I can see that students in those sections have posted videos on the other two assignments. I don't think any of my students are accessing this outside of the Canvas assignment, which is one of the things that Flipgrid lists as a potential problem with speedgrader in their directions. Anyone have any idea why I can't see students in the other two assignments?
