You can edit a session at any time — change the time, instructor, location, or any other detail. Open the session in the calendar and edit the fields directly in Event details.
The action menu
The ⋮ menu at the top right of Event details holds four actions:
Repeat — copy this session onto other dates, optionally carrying the enrolled clients across. See Repeating sessions .
Duplicate in parallel — create a second session in exactly the same time slot. Used when two classes run side by side, usually with different instructors. See Creating a session .
Send reminder — send a manual reminder to everyone enrolled, through your device's messaging app. See Sending a manual reminder .
Delete — cancel the session.
To move a session rather than change it, tap the blue Date and time link — see Rescheduling a session.
Cancelling a session
Delete in the action menu cancels the session. Everyone booked into it is sent the cancellation message, provided that template is switched on in Settings → Messaging. See Message templates.
Credits are never lost
Cancelling a session does not cost your clients credits. If credits come off at checkout — the default — the session never reached checkout. If you use Require product to book, where the credit is taken at booking, cancelling undoes the checkout and returns it.
Go to Overview and use Upcoming bookings. Filter the list down to the sessions you mean — by activity, day, instructor or date range — then select them and make the change in one go, rather than opening each one in the calendar.
