A. Look for an option in the app that allows you to view your upcoming appointments. If there is a 'View Details' or 'Manage Appointment' button, it may lead you to options for rescheduling. If this feature is not available, you may need to contact your healthcare provider directly to reschedule.

B. As an alternative, keep a calendar or reminder on your phone to track your appointments and manually reschedule by calling the provider's office.
