We have a few scenarios where a customer responds to a comment from a ticket but the response does not get logged in the comments and none of the participants receive an email. In some cases, it's one of the request participants that are responding and in other cases it is the reporter so I don't understand why this is happening. And, it's not the same person all the time. We have one customer that has no issues normally with replying and the reply gets logged in the comments but on this one ticket, it didn't get logged. And that is continuing to happen for different users and different tickets and even different projects. This is a major issue as we are missing responses from customers. Can someone please assist?
