Fixed Dates and Times
In order to prevent last minute bookings on your fixed date and time slots, you need to make your tickets go off sale before the event starts.
The way to do this is to head to Services then Listings.
Press Manage on the listing you want to edit.
Navigate to Tickets & Pricing.
Edit Ticket.
To have the ticket only be on sale for a certain amount of time, for example, if you were having a sale or early access event, tick that box. You can specify the days and hours before the start time that the ticket will go off sale.
Make sure to press 'Save Changes' after any edits.
To delete the ticket and remove it from all future sessions, press 'Delete Ticket'.

Navigate to Availability on your listing.
Go into By Appointment.
Scroll down and choose the Notice Period, i.e. how much time after a session is booked that it will take place.
Press Save Changes.
Group Requests
Head to Availability.
Click into Group Requests.
Choose your Notice Period, i.e. how much time after a session is booked that it will take place.
Press Save Changes at the bottom of the page.
