Phone will not connect to Chime Pro 2

Ordered 2 Chime Pro 2's on the internetSent them back. Got 1 new one on the internetBought 1 from a high street retailerNone of them will connect. Looking online, everyone is complaining about it not connecting to their wifi.None of the devices I have, seem to even put out a signal i.e:During setup, when the light is flashing green.I press continue on my phoneOn android it just doesn't find the device (tried 2 different phones)On iPhone if I entered the code manually it won't find the deviceOn iPhone if I scanned the QR code, it prompts me to connect to the setup network - then fails. - This always happens, even if the device isn't plugged in, it will show me the name of the network its looking for, showing that the name is coming from the QR code, not the device.On iPhone if I scanned the QR code, after a few tries to connect it tells me to goto the wifi settings and connect to the setup network manually.Setup network doesn't exist.Can't be seen on either android deviceCan't be seen on the iPhoneIf I use wifi analyzer on my android no named networks appear but 2 hidden networks appear when I plug a chime in. But neither match the mac address on the boxTried various combinations of calling support and holding the reset button.After support runs through their script they just tell you to get a replacement.What really gets to me is when support ask dumb questions, like how far is the device from the router, when my phone can't even connect to the device in the first place.Overall this has been an absolutely trash experience.
