unable to change to certain check in dates

Just joined and want to change my house that they can only check in certain time period. I already read the page https://partner.booking.com/en-gb/help/reservations/can-i-close-certain-dates-avoid-bookings-days-i-can%E2%80%99t-check-guests 

But I cannot find or see the button: no arrival anywhere.


Where can I find this button?


In Rates, Calendar, use List view.  On left hand side open up to see additional lines re Minimum stay and allowing check in for days.  You can use the Bulk edit to update to stop check in for specified days.  If you don't see the additional lines contact booking.com help team using Inbox icon on Extranet and ask them to open them up for you.
