I have 9 project boards feeding into a dashboard. I have added a timeline widget and in the “grouping” setting, I am trying to group by a dropdown field. The default grouping is by board, and when I change it to by dropdown field, it keeps the default grouping by board and adds a second grouping for the dropdown field. I have worked with tech support and no one can solve for this - possibly it’s not possible and is a feature request?
