Why don't instructors have the ability to upload a Turnitin assignment for students?
That's a huge weakness in your platform. That inability causes a loss in productivity for instructors. So far, today, I have wasted 30 minutes of grading time. The Canvas community indicated there was a way to do this, and was a complete waste of time. If this were being taught in Blackboard, I'd have saved and uploaded that students paper in a grand total of 2 minutes. That's on one student, that's also excluding others having similar issues and the connected emails.
