We have not assigned a default moderator to the reviews. The person who was authoring a review has left the organization. He is also being shown as the moderator of the review.
I'm the administrator but amazingly have no control on this situation. How do I close the review now? Our workflow forces us to close all the reviews before an item can be closed.
Change the permissions to you for that project to do Abandom/Complete review. And you can do all review changes.
