While grading via the Rubric, the student hit the SAVE button, which closed the peer review to any further grade point inputs.
How do I re-open the Rubric?
The assignment is closed, but the 'peer review' period is still open.
Daniel, greetings! Is the student sure that they can't get back into the Peer Review? I'd have them double-check these directions and see if they can or not - How do I submit a peer review to an assignment?
If they can't, then you could try removing the person from the review and then re-adding them manually. Or, you could also contact Canvas Support (Help link in Canvas --> Report a Problem) and see if they can help.
