Issue:-
Sometimes, the agent will see a traffic cop message that 'someone has just responded to this ticket. Please review the message before hitting send' even though there are no recent messages.
Resolution Path:-
Traffic cop works based on the note ID. If the currently sending reply's note id is higher than the recently added note ID then the traffic cop will pass. Incase the currently sending reply's note id is lower than recently added note then traffic cop will throw the above error.
This error will mostly occur on migrated tickets.
If the above error is visible on a ticket even without any recent replies then we can raise this with the L2 for further analysis.
To raise for L2 team, we can share the recent notes logs in the L2 ticket.
(Another way around to solve the problem is by removing the traffic_cop feature (based on customer demand) from the account through the backend script which will be done by L2.)
