The schedule is where students can view the studio's live class calendar, book classes and buy products; where teachers can request subs or book students into a class; and where the admin can edit and assign class details.
Depending on your permissions level, each user will see different options on the live schedule.
For admin directions on how to edit classes, substitute teachers, book students, and more, see the Schedule tutorial here.
For teachers, see the Instructor Portal tutorial here.
For students, see the Student Portal tutorial here.
