hi! new to the UM fam. have a small farm of UMS3s for a higher-ed college. earlier today I put x5 machines on Digital Factory; they all appeared and I renamed them. One of them then went 'missing' (grey, circle-X) from Digital Factory. At this time the 'connect' button at Digital Factory menu is non-responsive. See: https://photos.app.goo.gl/KRcPcjdHgTk7KDBa7
I have attempted rebooting, Reset Digital Factory (via Settings), and Reset all printer settings (also via Settings) - I'm not sure what else to do, but the button is not responding I therefore cannot connect the printer to Digital F
