I have various lights, smart outlets and HomePods that worked consistently when speaking to Siri on iPhone, iPad, or HomePod. The lights and HomePods have custom names that I gave them. In the last week, Siri on my iPhone but not the HomePods, cannot "find" the lights in the home. If I go to the Home App on my iPhone, I see the device and can control it with taps on the screen but no voice control will work when spoken to my iPhone. I just updated to the first public beta of iOS 13.4, but it was happening for sure on the build just prior too. Any theories as to what is happening?
