I am currently using the Trello Beta, so not sure if there is some functionality that is being worked on. However, I'm trying to set a Due Date automation to mark a card as Incomplete on the date it is due. However, it does not seem to be working.
I am wondering if Trello maybe disregards cards that are already marked as complete when the due date hits (but then, why would there be a "mark as incomplete" option?). Is there maybe something I am missing?
