After your assignment has been submitted for review, you will not be able to edit the submission or add additional documents until your reviewer has returned the review.
If you need to cancel your submission, you can do so only if the evaluator/reviewer hasn’t started his or her evaluation of your submission. Otherwise, you will need to wait until the review is returned to you.
To cancel your submission, first select the specific requirement or submission you need to cancel.
Once you have selected the appropriate submission, click on the Cancel Submission button (located in the upper-right corner of the page) and then click Yes Undo Submission and Unlock to confirm the cancellation.
You can then resubmit the documents after you have made the necessary edits.
