Hi Nikola, I'm busy setting up the Google sync on my site. It looks like it works well if I use the booking form to make an appointment on the site, it shows up on the google calendar.... But if I already have a date time with an appointment on my Google calendar, it still shows as available on the booking form. I have 1 location, and 1 worker: https://www.kevatarot.co.uk/book-appointment/ I want to be able to mark certain days/times as busy on my Google calendar, so that they can't be booked on the website. I think maybe it's just my settings that need to change, but I don't know how to make it work. Are you able to help please? Thanks Michele
