Wix Bookings Request: Changing Price Options for a Booked Service on a Clients' Behalf

Working on it
ETA: Q1 - 2024
Currently, it is not possible to change the price option for a client after they have already booked a service.  
You can cancel and refund the original booking and then manually create a new booking with the correct price option. 
We are always working to update and improve our products, and your feedback is greatly appreciated.
