I own a playbar, sub, 2x Play 1s, and a 1st gen Play 5. I switched to Google Wifi. The old network doesn't exist. I need to switch everything to the new network. The playbar and surround sound still work with the TV. I connected the Play5 and a Play1 (at different times) via ethernet to the router and followed all of the instructions. I cannot get it right. When I open the Sonos app after connecting a device via ethernet cable, the Sonos app doesn't "see" the connected device. So I keep getting the warning screen and there's no option to go to settings --> advanced settings. What do I do? Seems like it would be best to just factory reset everything.
