HomePods Jumping WiFi Networks, No More Mismatch Warnings, ...

My 2 sets of HomePod pairs keep jumping to other wifi networks than my phone and, at some point, Home App stopped reporting network mismatches and all wifi network info has been removed from my HomePods in the app so that I cannot even tell where they are connected.

I have IOS 16.6.1, 2 HomePods and 2 HomePod minis setup in pairs and an Apple TV 4K. I have 3 different home wifi networks (home, office, guests) all with your typical password protection. I used to get mismatch warnings in the Home App when the HomePods would jump to one of my other networks than the one in which my iPhone and Apple TV are connected.

1) Is there a way to make the HomePods stop jumping to the other two networks? I thought of changing the passwords to the networks so HomePods couldn't access, but I imagine that as soon as I log into one of them on my iPhone, they will again know.

2) Why is it that both Mismatch warnings and wifi info is now gone from my HomePod settings in the home app when Apple Support keeps referring to them as if they ware still part of the app. (see the attached phot. Apple support shows wifi and other information bellow Accessibility whereas you can see they are missing from mine).

It is extremely irritating to have to keep restarting my HomePods every time I want to listen to music in my home. There has to be a solution, please help.
