Before you begin...
When you change the duration of an event type, it will not apply to scheduled events that invitees have already booked with you.
From the mobile homepage, select the event type you’d like to edit.
Select the current Duration.
Select a new duration time. If the duration time you would like is not listed, choose Custom length of time and adjust the amount of hours and minutes.
NOTE: For group event types, once that event type has been scheduled, you will no longer be able to change it's duration. To change the event duration, you will need to clone the event type and assign a new duration in the cloned event.
