You're right, and it took me a while to figure that out. I have a lot of people message me asking about transportation, parking, and walking distance to bus stops, all of which is covered in the "Getting Around" section, so it's kind of annoying to have to regularly answer questions that I took the time to address in the listing. Another problem with the app is that it does not display the host's responses to reviews. A couple of years ago I had a guest who left a completely unwarranted negative review that contained several inaccuracies. Airbnb doesn't take down reviews - a host's only recourse is to post a response refuting the false allegations. But people using the mobile app can't see that, which is something that should be fixed, in my opinion. I didn't get any bookings for something like 2 straight weeks after that review went up, probably because no one using the mobile app had access to my side of the story.
