I have 2 Chromecast audio devices that were working perfectly until I
changed my Wifi settings. All other Google home devices were discovered
as expected but the Chromecast audio devices will not show up even after
several factory resets
UPDATE as this has been resolved. Apparently you CANNOT use a PIXEL
phone to achieve this goal. Others have reported the same. Worked as
expected on a Galaxy Tab 8. So it sums up to you can't use a Goggle
phone to setup a Google device EPIC FAILURE
