Can't make HomePod recognize my wife's voice.
I updated my HomePod's IOS today to iOS 13.2.1. It took a couple of hours before my HomePod's Siri understood requests for ambient sounds, but it does now.
I opened "Home" on my iPhone (there's a red "1" on the icon that I don't see what it points to) and clicked on the little house on the top-left corner. A pop-p menu shows "My Home" (checked), "My Home" (unchecked), "Home Settings", and "Cancel". If I click on "Home Settings", I get "My Home", "My Home (Guest), and see the "Home Switching on". I clicked the ">" next to "My Home".
I see two photos here, one of myself, and one of my wife. If I select me I see "Recognize my Voice", "Personal Requests", "Update Listening History", and a couple of "Allow Access To" settings all turned on.
If I select my wife's picture, I see "Add and Edit Accessories" and "Recognize My Voice" off. I can change the first of these to on, but I can't change "Recognize My Voice" on.
After discovering this, I held my wife's iPhone next to the HomePod, and have invited and accepted me with her "Home" application. (Always using the same network)
If instead of selecting "My Home", I select "My Home Guest", there are no personal options, but "This user can control accessories while at this location".
What do I need to do next?
