When clicking the link in an email notification sent from an automation, why does this say "No notification"?

Issue
I have received an email notification from an Automation with a link. But when I click the link it says "No notification". The notification is also not in my Home - Notifications tab.

Cause
The Automation includes an Alter Document step which has updated the document (for example, to update the Status). The document is no longer visible in the view that has been selected in the Automation to locate the document.

Solution
Remove the Alter Document step that is updating the document.
