Hello, have problem, messaged support but no answer from them already 3 days... 

I want do deactivate instant book. After i press "All guests must send a reservation request"  and then save, it goes to white page and i can't save changes. Refresh does not help, other browsers does not help and  From app i cant change it. 

 maybe someone had similar problem with Airbnb and can help me?
