sorry, I don't understand your support system - maybe this is the way to have a problem resolved.
I am using Appointments+ here: http://sedonaauraphoto.com/make-an-appointment/#app_schedule. Although my upper limit is set to 180 days, the appointment calendar only shows January. Clicking on next month shows no change.Check marking in Display Settings "Create an Appointment Page with current and next month's schedules" does not save.
Also, selecting a different service does not work. It still checks out with the first entered service.
Can you help?
