Nest audio not replying me

[TK5]

Hi
i having an issue the nest audio not replying me. 
It used to be that when you asked Nest Audio to turn on the air conditioner, it would respond with "Yes, opening the air conditioner" and proceed to carry out the action. Although it still completes the action, but now it does so silently without confirming with "Yes, opening the air conditioner" as it did before.

Is this an issue with my setting ?
i done reset still the same. 

do you have any advice?

Hi TK5,

Thanks for posting—let's get this sorted out. What’s the make of your air conditioner? When did you notice this behavior? Do you have other home automation devices linked to the Google Home app aside from your air conditioner? If yes, are you still getting Google Assistant responses whenever you control those other devices? Are you getting the same behavior if you control your air conditioner using Google Assistant on your phone?

Regards,
Alex
