Expired reviews currently can't be clicked on (as opposed to reviews unexpired), leading reviewers to believe that they can't act on it. Reviews are actually waiting to be completed in the old reviewer dashboard, but isn't made clear anywhere and the only way to notice is to go there, which you're unlikely to do if you believe you can't act on them (or don't know where to actually find them, as was my case).
