Since the TurnItIn LTI update in early 2017, I have experienced several issues relating to the new integration. One is the loss of the ability to add a rubric within Canvas that can be used in the Speedgrader system. This happens once the assignment submission type is changed to External Tool: TurnItIn LTI. If submissions have not been made, I can turn off the external tool, add a rubric to the assignment, and then turn the external tool back on. However, if submissions have been made, this is not possible, and I cannot create a new rubric. Is there another way around this?
