1. In the professional's file, go to Schedule › Absences.
  2. Choose the type:
    • Holidays: always full days.
    • Absence: full days or specific hours (a medical appointment, a training course…).
  3. Set the dates and, if you like, the reason.
  4. Choose what to do with the classes they had in that period:
    • Keep sessions: nothing changes. You'll need to sort out the classes yourself.
    • Block sessions: classes stay on the calendar but don't accept bookings. If you like, you can cancel existing bookings (with no charge and returning the session).
    • Replace professional: another professional takes those classes. Momento checks first that they're free.
    • Delete sessions: the classes disappear and clients get their session back.
  5. If you cancel or delete classes, choose whether to notify clients by notification or email. The reason is used as the cancellation reason.

Important: editing or deleting an absence doesn't undo what you did to the classes. If you deleted classes, they don't come back.
