I am having extreme difficulty finding the 'Convert to Work Order' button for cases. It's just missing from the ribbon - I can see the relevant process is activated and I can see the label text in the Ribbon Workbench but it will not display in any shape or form. We're on Field Service 7.5.xx currently which I believe is out of date but I don't seem to have the option to upgrade. Can anyone point me in the right direction here? Thanks.
