We have tightened how class booking limits and add-on time slots work.
- When your studio has the one reservation per class setting turned on, customers are now stopped at the moment they confirm a booking, with the message "You already have a reservation for this class." This also blocks booking more than one spot in the same class, and it holds even if two booking attempts arrive at the same time.
- Studio staff and admins can still add a customer more than once to the same class when they need to.
- Add-on time slots now show whenever the date range and available spots allow, instead of being hidden by the booking cut-off window.
