Hi! very happy to discover this endeavour, try it out and post helpful bugs comments and suggestions.

In this case I notice that after you set up the slot format of the appointment type, then navigate to the public page to book an appointment it displays all slots as available, despite I have several already booked that would conflict.

In the case the app is not capable of fetching the events from the host calendar it should display some sort of error on the web interface and/or the server.

I'm on OSX Catalina. The app was installed and set up on localhost:3000.
