RBR50 network installing PurpleAir sensor

[pkovaric]

Has anyone had success in setting up a PurpleAir air quality sensor in an Orbi network?  I'm running all the current firmware, but the Purple Air will not join the network. I've tried this https://community.netgear.com/t5/Orbi/2-4GHz-device-won-t-connect-to-Orbi/td-p/1880621, but it still won't join.

At which step in the WiFi instructions does something "go wrong"?

It appears from these instructions that the common "bug-a-boo" of the phone having to be connected at 2.4G is totally avoided by this product.  i.e. The phone connected to a web server on the device and enters the WiFi SSID/password directly into the device.

My pudgy fingers sometimes have trouble entering passwords on the tiny phone virtual keyboard.  Does this device allow the user to view the password being entered (rather than showing 'dots')?
