Getting started with the extranet | Booking.com Basics

How can I get started with extranet I want to give u my bank detail

1. I cannot find the sync calendar button anywhere under the Rates and Availability tab.
2. I cannot find the bank details button under the Finance tab.
Please support me I have sent the feedback but have not since received any response.

He tenido una pésima experiencia trabajando con Booking. Las políticas de cancelación, formas de pago, identidades verificadas de los huéspedes y seguro para anfitriones no existen! Ademas de una horrible atención al cliente. No lo recomiendo
