What is the best way to request support by creating support tickets?
Ideally, you should create individual support tickets per each issue. Tickets are attended on by one using KANBAN technique. Therefore when issues are mixed in a ticket it takes more time and will not be able to resolve ticket until multiple issues are resolved.
One ticket has one issue to resolve per one vehicle or site can be attended promptly and in a structured manner. If anyone ticket required priority can be requested selecting a high priority option.
