Put a class you cancelled by mistake back on the timetable.
Needs the Manage bookings permission.
There is no button for this. The calendar cancels a class and offers nothing that reverses it, so a class cancelled by mistake stays cancelled as far as the dashboard is concerned.
The assistant can put it back. Ask it — “I cancelled Thursday’s 7pm spin by mistake, put it back” — and it will, as long as you are someone who could have cancelled the class in the first place.
What comes back with it:
A class that was synced to Urban and cancelled there was cancelled on their side too. Restoring it here puts it back on your own timetable and your own booking page only — Urban still believes it is off, and that has to be sorted out with them.
Add the class again as a one-off, from Actions, then Add event on the week it belongs in. You will be rebuilding it by hand, and anyone who was booked on the cancelled one will need booking again.
