Do i have to click the pre-approve/decline button for an inquiry?

[Annette33]

I'm not on IB, but the regular "old" booking system. In contrast to a booking request (decline or approve within 24 hours)  I thought that an inquiry just needed to be answered to in a timely manner in order to be  recognized by Airbnb as a valid response, but I now see that after I send off my reply message, the red pre-approve/decline button remains highlighted in red under the inquiry in my inbox, as if I still needed to do something about it, possibly meaning that I can't just answer the inquiry with a return message, but that I also must choose between either preapproving or declining. Is that correct?  I'm afraid that if  I don't activate the button, my answer will not be sufficient enough to be counted as response in Airbnb's system.

Hey all

updating the thread for anyone searching this question

seems like you don’t have to click to maintain response rate
