Displaying the day/week/month tabs

Hello,

If you are talking about this here: https://demo.simplecalendar.io/fullcalendar/with-google-calendar-pro/

Then that is part of the FullCalendar Add-on and not in the free version.

If you already have the add-on and are having trouble with finding it please open a support ticket here: https://simplecalendar.io/contact/

Thanks!
