Getting intermittent home hub not responding

7 home pods in the house. Pretty light duty. Lights, intercom, door locks. The kitchen unit is the “home hub.” About 6x a day I get an alert stating kitchen not responding. It then designates my daughter’s HomePod at the hub. Usually within a few hours I get a message that it has switched back. There doesn’t seem to be any interruption in functionality, but it sure is annoying. Should I start with just removing kitchen and start from scratch?
