One of the members of the Service Desk team is unable to see all the projects in the dropdown.
Using the permission helper I've checked any and all permissions that seem even remotely relevant. He has the Link Issues, Browse projects, Assign Issues, Create Issues, Edit Issues. Modify Reporter, Move Issues, Resolve Issues, and Transition Issues. He also has those permissions in the intended target project.
I can't possibly think what it could be at this point. Is there anything I'm missing?
