Adding a customer to several dates of a class now checks that their pass covers every booking

The Add customer window on your class schedule is now clearer when you book a customer into more than one date of a repeating class or course.

• The tabs are now called Customer and More classes, and they sit beside the class name and time.
• Under More classes, each date shows its points, length, and whether it is full or cancelled. The class you started from is always included.
• The total number of classes, and the total points if you use points, is shown at the top.
• If the chosen pass doesn't have enough points or visits for every date and every attendee, you see a warning with how many are needed and how many are left, and the booking can't be saved until you change it.
• If something is missing when you press Save, you are taken back to the Customer tab so you can see what needs fixing.
