No problem! Our system is designed to overlook one-off misses. If you have more PHs coming up that you will not be able to make, be sure to remove them from your schedule ASAP. Read the Priority Hours section of the Tutor Guide for more information about our PH system.
Please note that even though you can't tutor from your device, you can do pretty much everything else using your mobile browser (dropping Priority Hours, checking reservations, etc.)!
