There may be an occasion when you need to approve the proof on behalf of the approver, for example:
The approver contacted you by phone to say the proof was approved and they don’t have access to their computer right now
The approver sent you a small to-do that you aren’t going to action, that proof they received was the final version.
To approve the proof manually
Click the cog icon on the proof tile to open the manage pane.
Select approve proof.
Add a message if you like and click accept & continue.
The approver and any other proof owners will receive an email notification that a manual approval was given.
