Azure DevOps Boards - how to change the color of workitem by using a criteria rule

The items on a Azure Devops board can change color when a criteria rule is met. In the video I show how to change a workitem to red when it has not been changed for greater than five days.

Hi! Do you know if it's possible change the color of the card when it' has a child for a certain type? For example: "impediment"?

Hello. Here, the AD doesn't allow me to put any other value except a day from calendar. Just like you did, @today, not allowed. Do you know why?
