I’m not sure why this isn’t working… I have my To-Do Bar visible, which shows a small calendar (with bolded numbers for dates I have scheduled appointments), a list of tasks, and a list of appointments. But my appointements section isn’t populated. I have a meeting in 30 minutes, but it’s not showing. Under Options, I have “show 3 appointments” selected - but…nothing.
Right-click on the top bar (right where it says “To-Do Bar”) and ensure that “Appointments” is checked. If it’s not, you won’t see appointments even if you have Options set the way you describe.
