Workflow and status overview is on top of the review page, but buttons to go to the next phase or wait for others are located at the bottom. From a user point very bad. My proposal would be to have the buttons both on top and at the bottom of the page.
Possibly, the Next Steps box doesn't show up till the review is started, and then it is at the top of the page.
From my perspective it seems logical to have them where they currently are at the bottom of the window, which forces the users to at least scroll past the comments and review materials to get to them. Including them (additionally) at the top IMO could just be a shortcut for users who want to approve the review without doing anything, or could possibly help enable that undesired use case.
