All private meetings on the agenda have a duration that is limited by time slots.
The time slot duration for meetings can range from 5 to 60 minutes. Also, it can be adjusted by the organizer in the Setup section → General tab → Event details.
Please note that time slot duration change will be disabled once a meeting has been scheduled (including tests in the draft mode of the event).
In such situations please contact our support team at [email protected] or in the chat on the website.
