You may be asked to add a reviewer to an older version of a proof if they weren’t included on the proof at the time.
As the proof owner, you can either:
- Add them as a reviewer into the workflow in the proof’s info pane.
Note: Because the proof has a new version they won’t receive an invitation to review the proof since the red pen is no longer available.
- Add them as an owner (they will have the same priviledges as you do)
To add an owner, follow the steps in this help article.
