Total failure to set up a reset chromecast on my pixel 4a5g. Kept suggesting I needed Device Utility to activate device. After wasting half an hour I tried my iPad. Worked first time. Google still has a lot to learn about its own devices. In response to the Google response: I DID download the Device Utility and was sent round in circles. Why does the Home app work first time on my iPad, but not on my pixel?
