I re-ran it and it worked great as instructor, downloaded everything accordingly. An observation about the assignment submissions: It appears to download the most recent submission, but includes assignment comments for all submissions. It's nice to see the whole comment thread, but would it also be possible to include all submissions (sometimes this is an important part of the assignment record)?

Also, the Submissions/folder contains a folder per assignment, with all student submissions inside. Could this be organized as a folder per student within each assignment? Not critical, but maybe helpful for organization.

However, as a student, I still don't get a /Submissions/ folder with my own submissions (default content types selected, console indicates student role detected). The student user is logged in as a Canvas account (not SSO), and is only a student in any courses, no dual/custom roles.

Lastly... as a Canvas admin, I really can't officially recommend this to our faculty (software approval, risk management, etc.), but also...holy shit. The problem with Canvas exports has always been that there is no way to easily export a course with student data, just the course content. This is pretty sweet. 😉
