If you know you can't make it to a lesson, let the student know as early as possible and suggest another date and time.
Ask the student to reschedule the lesson if there are more than 24 hours till its start.
If there is less time and the student doesn't have this feature available, contact Support.

Students can reschedule any lesson 3 times on their side. When they do, they choose a new time slot in your schedule, so keep it up to date.

If you can’t make it because there's too little time before the start of the lesson, there is a way to avoid it. You can allow students to book lessons no later than 15 minutes before they start. Or even no later than 24 hours 😎
