Sorry to hear about the trouble, @rhutchins. The mobile version of the site doesn't display the calendar in the same way it does for desktop, however it should be displaying your upcoming appointments for today by default, and you can select the date at the top to view past and future appointments.
Additionally, there is a link at the bottom to of the page to create new appointments. I know it's not as good as the desktop version, but you should at least have those basic capabilities. Thanks for taking the time to post, let us know if you have any other questions.
