I struggled for months to get my Chromecast devices working. Factory resets. Router reboots. The whole song and dance. No matter what I tried, the Google Home app would not see the device. Never had time to see it through until today. And I solved it!
Someone said to turn off band steering. So I did. No luck. Then I unplugged all Eero network extenders. That did the trick! Chromecast setup is done and the device is working! I wanted to memorialize my success here in case anyone else is having the same trouble. I’ve not turned band steering back on, fwiw, because so I don’t know for sure if it was or wasn’t part of the problem.
