We have just started using Canvas this year and are having trouble with assignment submissions - significant problems that may result in us only using Canvas for this year and then looking for an alternative. We are hoping that it is user error on our part rather than a faulty platform!

The primary issue that we have is the speedgrader usually not showing that a student has submitted an assignment when they have and not showing the submitted file in the speedgrader window for marking.

The assignment inbox shows there is a submission (and lists the uploaded file name and submission date/time), analytics shows that there is a submission, but not speedgrader.

Sometimes it does work. One teacher added me as a student to their course and I submitted a google doc. My submission shows up in speedgrader, and can be viewed in speedgrader, but not the submissions of the students.

This is happening with Google Assignments and also with TurnItIn.

Any ideas?
