After iOS26 update Siri no longer recognizes voice commands to control Apple TV's

I have (5) Apple TVs in my house, and (4) of them I've had no problem controlling with Siri. You know, all hands-free, by saying: "Hey Siri, turn on the Living Room TV," "Hey Siri, Mute the Main Bedroom TV," et cetera. However, after the iOS 26 update, I can no longer do this hands-free.

Now, when I say "Hey Siri, turn on the living room TV," I get a reply that says "Which TV..." and it reads out my TVs and shows a list of them on screen. I say "living room" and then it comes back with the same list and asks me again, "Which TV..." followed by the list. I can physically touch the TV in the on-screen list, and it will perform the action; however, it will never recognize the voice command.

iPhone 14/15 Pro Max are both on iOS 26, and all the TVs are on TVOS 18.7.

Is anyone else having this issue? Has anyone figured out how to work around it?

TiA!
