If you’ve created a Round Robin, you should note that they do not automatically start assigning tickets, a Round Robin makes a new Action available in your Automation Rule Builders.

For example, to start assigning Tickets based on a Round Robin, you need to create a new helpdesk Trigger that uses the Round Robin in its actions.

To start using a Round Robin in a Trigger you will need to go to Admin > Business Rules > Triggers. For more information, you can check out the Admin Guide.
