If you are viewing your schedule in the mobile app and are unable to find the "Book Appointment" button, it is likely because you are viewing your Personal Schedule in the mobile app rather than the Business Schedule.
You can confirm this by reviewing the text at the top of the schedule, just above where the month is listed.
If you are viewing the Business Schedule, the Business Name will appear.
If you are viewing the Personal Schedule, you will see My Schedule at the top of the page.
You can toggle between the 2 schedules by selecting the menu option in the top left corner of the app, then selecting the down arrow below the "Dashboard" option.
