The start date is not taken into consideration when grouping by the due date in the list view.
I need both the start and due dates taken into consideration. I need it to always group by the start date, and if a start date is not available, then group by the due date. I find this very essential to make sure that I don't miss my goals.
I am currently using TickTick, which handles start and due dates very well. They also have a countdown mode that I want to see added to ClickUp.
