Good morning;
I am using easyappointments-1.5.0-dev.4.
The following are screenshots of what is occurring. I have changed the "First day of the week" - that was my first troubleshooting step, but Thursday and Friday are still the days that are blocked out when it should be Friday and Saturday.
The time zones are set to New York -5:00 for the server, the site, and the providers.
