Planner Calendar does not update in Outlook

I recently saw that Planner had Outlook integration now so I decided I would finally give Planner a chance. I created a task in Planner and then I clicked ''add plan to Outlook calendar'', the calendar was added to Outlook and I saw the task I created as expected. However now when I add new tasks they do not get added to the Outlook calendar, all I see is the first task I created before syncing Planner to Outlook. Even the iCalendar link provided dosent work. How is Outlook integration for Planner supposed to function? Any idea why the calendar isn't updating? Thanks!
