When transitioning a ticket to a new workflow state, we have it configured so that the agent is prompted to add an optional comment and attachment. After adding an attachment and comment this way, the proper notification is sent to the reporter, but it does not include a link to the attachment. However, if the agent were to comment directly on the ticket and add an attachment, it would include a link in the notification. Is this expected? If not, why is there a difference in behavior?
