So, we have encountered a few assignments where the Speedgrader presents the teacher with the "Empty Course" page, even though the course is not empty.
I have discovered two New Quizzes in the same course where this has occurred, despite multiple students being assigned (at Module level, which passes the permission down to the Assignment level, and shows in the Assignment settings as inherited from the module).
Teachers discovered a solution, which was to assign another student, as this then seemed to trigger the Speedgrader to pick up the entire student list. The problem has appeared some time between the end of November last year and the first week of February (as one assignment from November had been marked and given feedback, but it was no longer accessible when it was checked by teachers recommencing in the past few weeks).
I can't find a pattern - there are other quizzes in this course that have the precise same settings that have not been affected, but maybe I am missing something. Could it be user error somewhere? If I unassign the students (even if they have completed the quiz), this page is what shows up. Could there be a clash between Module and Assignment permissions???
Happy to seek Canvas Support support (!) but thought I'd check if anyone else has experienced this before passing it on.
