I've been trying to setup our next-gen Service Desk so that the priority is automatically assigned based upon impact and urgency. I've attempted to create a workflow to reflect this, but the instructions only reflect how to do this in the previous generation of the Jira Service Desk. The part which is unclear to me is how to setup the workflow. The automation side of it should be okay, but I'm currently not able to set custom rule to to edit the priority (as the option isn't available) due to the absence of the matrix.
Is anyone able to help, please?
