I added this today to the updates website:
Pg 272 (Oct 2019 edition of Amsterdam & The Netherlands) -- Public Bus #397 -- a) Drivers do not sell tickets, and b) bus lane change. To buy a ticket, look as you exit the terminal for a red van labeled "Amsterdam Airport Express, Bus 397." (Probably parked on the sidewalk.) Buy there and then proceed to the line of people waiting at lane B17 (not B9 as shown in the book version above).
