Then the fact that someone messages they have changed their mind not to book, i am required to respond to this to prevent a hit on my response time.? Who has the time to carry on a conversation with a non renter to keep our response time @ 100%? Mine went from 100% to 97% with no response more than 10 hours, but yet, 2 un replied to messages that had no question or need to reply, like a Thank you for accepting their request to book. Does a thank you really require a response? Airbnb needs to relax on this.
