I thought TidyCal would help me manage different booking types and help me to not book two sessions onto one timeslot, but sadly TidyCal won't read my calendar, well it reads the calendar, but it does not respect that a timeslot is already taken by another booking. TidyCal would still try to fit a booking into the taken timeslot.
I am trying to fix this and find a workaround for the past 2 hours, but there isn't. I will have to manually block a specific time, what makes TidyCal useless for me.
