Reviews can be canceled from an account with “Oversee Reviews” permissions. (See "Q: How do I assign Workspace Manager and/or Review Manager permissions?"). To cancel a Review, please follow these steps:
From the Review menu in the left panel of the account home page, click the View all submissions link.
Click the Manage reviews link to the far right of the Workspace for which you want to cancel a Review.
Locate the Review you want to cancel.
Click on View/Edit for the Review you want to edit.
If the Reviews have already been reconciled, click Cancel Reconciled Reviews.
Click on View/Edit, then click Edit Review and edit the score accordingly.
If you would like to see your changes, click View/Edit again. Note: you will need to reconcile the Reviews again.
