Yes, you can reschedule your session, but this must be done at least 24 hours in advance.
To reschedule within the deadline, log in to your account and go to "My Sessions" or to the " Control Panel" , where you can view your upcoming sessions. In both cases, click on the session details , select the "Reschedule" option, choose the new available date and time and confirm your new appointment day.
After confirmation, you will be able to view your new appointment date in "My Sessions" .
