Two fixes for customers booking with you.
- When a customer picks a time for an appointment-type class, the number of attendees set on that class is now used for both the available-times check and the booking itself, instead of always booking for one person.
- Customers using an out-of-date device or browser now see a short message in English or Traditional Chinese asking them to update, instead of a blank screen. On iPhone or iPad the app now needs iOS 16.4 or later; on a computer, the latest Safari, Chrome, Edge or Firefox.
