I'm not keen on coincidences but today after updating the BT Whole Home WiFi app my additional disks have dropped off of my setup. The only one still working is the one connected to my BT router. Tried removing the disks and re adding, which appear to work successfully i.e disks go to solid blue LED. Also tried factory reset on disks, but still the same thing. As soon as I move them to their previous location, which worked fine before, they both go to a solid red, disconnected, status. Worryingly the additional disks look to have automatically downloaded a firmware update as part of the process of re adding. Anyone else experiencing the same thing?
