Arlo Baby died. Orange LED came on but does not blink? Unable to add them back.

Hi. We have two Arlo Baby cameras. We unplugged them to take away for a holiday (we never use battery). On plugging them back in a day later, the orange LED came on but did not blink. It disappeared after 15 seconds. I could not then connect them to the Arlo app (so deleted the two cameras and tried to add back). When adding them back, they would chime when scanning the QR code but would not be discovered by the app. I’ve tried power cycling them. We are on the same WiFi network, full network signal. I’ve deleted the cameras and Arlo app and tried to re add Cameras. I’ve tried to factory reset. I’ve plugged into different power sockets in the wall. They just don’t seem to be responding but are on and seemingly alive. What am I doing wrong and what should I try?
One was bought in 2018, the other in 2019.

Same problem here.  Still not fixed.  The Arlo team's only suggestion is to factory reset the device, which does not work.
