I have 3 projects where the Epic is automatically hidden from the "Board" view for everyone but I cannot replicate it in a new board. Hidden from anyone i mean that any user that views this board does not have to apply the filter to remove the Epic from view, it is automatically hidden. We do however want the Epics to show in the "List" view.
This board was created by someone who is no longer with our company so I'm not sure what they did. I have compared the boards and it seems like they are the same.
The new project, that I just created, is from the work management > blank project template. My company has the Standard plan and I am an Admin.
