OK, BT issue solved, and this solution may help others.
Go into the Google Home app on tablet or phone go into Devices and tap on the the 3-dot menu for the GH you want to configure for BT, go into Settings. Since none are configured, tap on paired BT devices then tap enable bluetooth. Have music playing on mobile device and turn on BT and select the GH device. Done; the sound should be coming from GH. I did same for my second GH. Done. You can enable the GH BT with all your mobile devices. I even set up my cell phone, too. Very handy if listened to Tunein app on phone and I want to hear it on GH (or even Alexa device). All very cool.
