When I look to 'My Calendars' on the left side, while I see other calendars but not the "Task" calendar. I went into settings and there is no "task" calendar to select. I am obviously missing something fundamental but I have spent much time looking without figuring it out.
Do you see the "Reminders" calendar? If so then you can click the dropdown options for this and "Switch to Tasks". You can toggle between "Reminders" and "Tasks", but you don't seem to be able to display both at the same time.
