WiFi Pod (black): failure to install

Virgin recently sent me a WiFi pod (black) and I've expended several hours trying various things to get it installed, without success.

• I have a SuperHub 4 and I'm using the Connect App on iOS 26.2 (iPhone 15 Pro Max).
• The Connect app reports that installation has failed, and the Pod exhibits a flashing (dull) white light in the lower right corner.
• The Pod serial number on the device matches that expected by the Connect app.
• I've rebooted the SuperHub and reset the Pod.
• The Hub and Pod are in the same room, for setup purposes.

Some screenshots below ... any ideas?

Thanks,
Peter
