Approve needs a login
The Approve and Reject buttons in the proposal email open the Quote History page, which needs a logged-in customer. A guest can submit a quote and receive a proposal, but cannot approve from the email. The buttons only appear on Business and up, with Auto Convert to Draft Order on and the Quote History page published. A buyer who is not signed in is sent to the login page and must click the button in the email again after signing in.
