Prevent Quantity Changes in Shopify Cart After Booking with Cowlendar

When you enable the "Lock quantity after booking" feature in Cowlendar, customers will no longer be able to change the quantity of the booked service in the Shopify cart. This helps prevent accidental overbooking and ensures each reservation is handled exactly as intended, providing a smoother and more controlled checkout experience
