Update the classes you teach right from the instructor portal — name, description, capacity, price, room, and visibility. Capacity changes apply to your upcoming sessions. So do price, visibility and online changes.
In the instructor portal, go to My Classes and click the class you want to change. You can only edit classes assigned to you.
Change the name, description, duration, capacity, price, room, or the Public / Online toggles, then click Save Changes. This now works for every class you teach, including sound baths and other one-off style classes.
When you change the capacity, all of your upcoming (not-yet-held) sessions for that class are updated to the new number automatically, so the schedule and booking pages show the same limit.
A new price, the Public toggle, and Online (with its link) are carried to your upcoming sessions the same way, so the schedule, the booking pages and the amount charged all match. The confirmation says how many sessions were updated.
