In the last 10 days, two of my three homepods have stopped responding to commands. When I say “hey Siri,” I get a brief flash on top that goes away. They don’t follow commands. When I hold my finger on the top to bring up Siri, it still isn’t listening to commands. Is this a recent update issue? Anyone know how to resolve this? I’ve tried unplugging them and restarting her using the Home app, but no luck
