@Victoria794 I'm not sure what you mean by not having the option anymore. I think you are confusing Inquiries with Booking Requests. With an Inquiry, you are asked to either Pre-approve or Decline, but in fact you don't have to do either, you just have to message the guest back within 24 hours in order not to be penalized. Dates for Inquiries are never automatically blocked. If you feel good about the guest, Pre-approve, which means they can move on to booking.
Booking Requests, for which you are asked to Accept (not pre-approve) or Decline, have always had the dates blocked until they collect payment from the guest, the guest has 24 hours to pay and the booking will be confirmed.
