@mention notification not sent if existing work note with a @mention tag has been copied into a new work noteDescriptionThe OOB notification "Activity Stream @Mention Email" should be sent if the @mention functionality is used as described in the documentation: https://docs.servicenow.com/csh?topicname=c_NavigationAndTheUserInterface.html&version=latest However, the notification is not triggered if you copy an existing work note which contains an @mention into a new work note and post/save the record.ResolutionThis is an expected behaviour since the mention in the worknotes is being inserted as @[username] and it is being posted as @username. For this reason, if it is being copied, it won't be inserted in the right format and the notification will not be triggered.
