Having difficulty connecting smart plug to google home. Connected first on the Kasa app and linked to google. But plug device never shows up in google to connect. Did the same with Tapo and the same happened. Tried connecting via Google home directly and it wants me to scan a QR code or put in a 8 digit number. However there is neither!! So can't get past that without a code.  Any instructions that are current with the latest google home app?
