Hi, i have a working installation of EA sync with a google calendar, push from calendar to EA work perfectly as i correctly see my appointments in my administration interface, on the right location for the right worker. However on the client side the time slot are not greyed out, which is a huge problem for me (as it allow people to make reservation while worker is already busy), is there a special configuration to set or a workaround to "grey out" time slot using calendar ?
