First of all, there is no way to display the Boards option in the Sidebar in the new UI to the Create Boards page that lets you create boards across projects yoururl.atlassian.com/jira/boards. There is no option for Boards. Ok, so I navigated there but why is it gone?
Then, when I did create a Board in my project, using a filter that includes multiple projects and excludes "done" statuses, when I click on Timeline or List, it's not using the filter on those views, it's only showing me tickets in the project.
I created the board for a reason and it includes tickets across projects. But there is no way for me to have a board that does that?? This is unworkable.
