A reviewer's option in a workflow step. Clicking 'Return' regresses the workflow to the previous step.
In a Content Flow workflow, the 'Return' button indicates your disapproval of a draft page’s content. Adding a comment along with your 'Return' click helps to convey to reviewers of the previous step what needs to change before the page should advance again.
Upon disapproval, the workflow returns to the previous step, and reviewers of both the previous step and the returned step will need to re-approve for the workflow to continue.
