I clicked on the "Exporting" button in Gradebook as I've always done to get the gradebook template, but it won't bring up my CSV or Excel file. The "Exporting" button is now just grayed out for every course that I've tried this under. Now I can't even import grades for these courses, the circle just spins and spins when I try and I am never able to get to the page that asks you to browse for the grade file you want to import. It's been like this for several hours. I've tried logging out of Canvas and logging back in, shutting down my computer, etc. Nothing is helping. How can I post grades on Canvas for 200 students without the Import or Export features working?
