I use the "classic" theme.

If you make a reservation (even if you just select the date and time) using a smartphone as shown in the following two examples, you will not be able to return to the previous page.

If you embed a widget on a web page, you will not be able to return to the previous page.

If you paste the Bookings link on the WEB page and go to the reservation page, you will not be able to return to the WEB page.
