This change to Config Editor brought both the Devices/Printers panes back for us. All our MFPs showed the 'Stopped' status and our In-use license count was still at 0. Forcing a sync from the admin portal refresh the status of all the devices to 'Started' and we are seeing an accurate count for licenses.
Makes sense to me that this was caused by the issues with PaperCuts cloud licensing. I can't recall if this value was set to PRINT before the outage or not though.
Thank you Alastairb25!
