Many problems with Appointments+ (dev site)

I’m having a hard time getting the core functionality to work except on the page created by the plugin (https://lowestcostwebsites.com/make-an-appointment/). The instructions on the plug in are from 2016 and reference things that aren’t there regarding the shortcodes.

There are some funky behaviors with the shortcode tool, as well. The default “Monthly Schedule” shows the title with <h3> tags in it, but if you modify any of it it breaks. The default is the only thing that works.

My client is providing child care services which are sold in blocks of time, and I’m not sure how or if I can implement this on specific provider pages. Once again, the lack of documentation on shortcode options is a problem. ‘Monthly schedule’ for a specific provider only allows for one service, for instance.
