Editing an entire class schedule is current functionality that we don’t offer. With that said, we do offer the ability to override some attributes of a single class schedule.
To override a class schedule, go to your class calendar and click on the class you want to edit. From the popup, click edit and you will see a slide out that contains all the fields that you can edit. Again, to be very clear, this will only edit the one class you selected. Not all classes in that schedule.
If you want to edit all future classes, we would recommend cancelling the schedule and creating a new one.
