My students' submissions are missing from the Assignment/SpeedGrader
If your students' submissions are not appearing in SpeedGrader for an Assignment, the most likely reason is that you have re-assigned the Assignment to a small subset of students.
Rest assured that the previous submissions still exist. They are just hidden from view due to the Assign To settings in the Assignment.
When changing Assign To settings, if you remove Everyone, giving specific students or sections a new date, you need to ensure that the Assignment is also assigned to Everyone else. Click + Assign to (at the bottom of Assign Access) in order to add differentiated dates for different individuals, sections, or everyone else.
