I'm using Jira Service Desk to manage support requests from customers. They log in to the portal and can raise a ticket. I want them to be able to see all the tickets (open and closed) once they have logged in. I've set the permissions for the project so that "Service Desk Customer - Portal Access" can "Browse Projects" (which seems like the relevant permission to set), but this doesn't seem to have made any difference.
What am I missing?
