In the old app the Calendar layout had the ability to change the default view to display as a list view. This was extremely useful because it allowed tasks to be grouped by day when viewed as a list.
With the new app, trying to do the same thing with a List layout and grouping by date doesn’t work when the date also includes the time because it creates a new group for every different date AND time.
Vote to reinstate the list view feature for Calendar layout. With many votes, it may get reinstated soon.
