Speaker Groups Disappearing

[Drewch]

Speaker Groups that I create in the Google Home app disappear as soon as I leave the app. It will let me delete groups but new groups don't save.

I have tried restarting my phone, restarting the devices, restarting the modem/router, and removing & reinstalling the Home app.

So it seems like it may be specific to two of our Nest Minis in particular. We have four Nest Minis and I seem to be able to create groups with two of them (call them set A) but not the other two (call them set B).

And if I create a spreaker group with one device from set A and one from set B, the group doesn't disappear, but the device from set B disappears from the group.

The devices in set B work otherwise. They respond to voice commands, stream music, etc.

They all have the same firmware version (375114) and cast firmware (2.57.375114).

Also, the issue has persisted for several days.

None of my Groups are showing up in the Home app. I can see them in Spotify, but cannot even see them to edit them in the Home app. Av not add new groups as the device list is just empty.
