Maybe that the chat box is somewhat hidden
Sure they have many products so then lets instead type chatGPT into google and go the link. Now I get to a page where it tells me to login on the side. Now I click login. Now im at an auth page. Next I get in. Now on the left I have about 60 tabs showing "new chat".
There is just a ton about the design that makes it inaccessible, difficult to navigate to the actual products and get to results. Im no expert in this matter, but it is much closer to Snapchat level UI intuitiveness than it is to Airbnb.
