This is related to changes Google made, as detailed here:
https://workspaceupdates.googleblog.com/2019/03/threading-changes-in-gmail-conversation-view.htmlEssentially, with those changes, Google will need in addition to the same subject, the email reference headers to consistently refer to the same message ID for it to be threaded.
It would be great if WHMCS could add the reference headers so that mails regarding the same ticket show up as conversations in Gmail.
