Does the latest version still support this code? The shortcode is outputting products but a lot more than expected, for example I've tested it for a range where only one should display and we have 8 showing with this.

Saved me a right nightmare of trying to find the relevant code in their plugin. Only update needed now is changing "WC_Bookings_Controller" to "WC_Booking_Data_Store"

How to use code in home page?
Thanks,
