I'm having trouble understanding why we are not receiving customer replies under tickets. When we add a comment to a ticket, the email seems to go through, however, we do not receive replies from customers. I've reviewed the permissions, the notification scheme, the request type is "Emailed request" which is linked to an email channel. I've also checked the Processing log and didn't find anything.
Upon receiving a ticket I changed the reporter to the preferred one, could it be causing this?
Is there anything else I could check?
