Your site responsiveness has been a frustrating problem forever now, but, like everybody else, I always forget to mention it with Airbnb feedback surveys is because the first and only thing we remember is hosting of guests, communication, payments.
I use only the latest, fastest computers on extremely fast internet connections and yet myself, my guests, and everyone I know who uses Airbnb find ourselves complaining at how delayed and slow your website and the App is.
We always assume there must just be wifi or ethernet traffic slowdowns so we fail to suspect the true culprit: Airbnb.com itself. Even typing this form and making changes is frustratingly slow.
Whatever you're using clearly cannot handle the number of users on your platform.
