It was a nightmare for me as it looked my wife out of our homes: we updated hers and it wouldn't let her onto our other home overseas until I'd updated Home. Except one of the HomePods there was stubbornly refusing to update to 16.2 so it all stalled.
Deleting it - so I'll need to re-add it when we're back there - and ungrouping two sets of HomePods allowed me to update Home, but I still can't access her home and vice versa despite us both inviting the other.
