Had Google Nest wifi setup for over 1 yr. Network displayed in the Home app and I was able to manage network and devices on the Home app until recently. Have the Home app linked to the same Google acct. All devices are still connected to the Google Nest wifi and working fine. But, the Home app no longer displays the network and devices nor does it have the option to connect or setup any wifi. The access points now appear as speakers. The problem is only with the Home app. I have installed and re-installed the app 4 times.
