Siri on iPhone 16 is LESS responsive than on 12

I’ve tried everything I could think of and “reset” Siri and my phone a few times. No matter what I say, Siri or Hey Siri, my iPhone 16 is so much less responsive than my iPhone 12. And when she finally does respond, she says. “Uh huh” and I have to start over! Quite frustrating. I should have never “upgraded”. This “upgrade” is frustratingly a downgrade
