I love that it's easy for my clients who are in different time zones from me! It also syncs with Google Calendar so we can see each other’s availability/schedules at any given moment throughout our day (or night).
The calendar has been updated since last year but there was an issue where events would be marked as "busy" even if they were available or no longer active - this made scheduling very difficult because you couldn't tell which ones should have "Busied". We use both of these features together when booking client meetings; however sometimes one person will schedule something before another without realizing what happened until after things get booked up months later!! This makes finding someone open during certain times extremely hard unless everyone knows about all upcoming appointments beforehand instead just relying upon luck & google searches alone like us.
