I spent the last 3 hours Googling this issue but it seems like all info is either outdated or doesnt work.
I have many projects (10+). I want to have one sprint board to manage all projects. I created a general Board in my "General" project. Now, I am trying to move the backlogged tasks into the General project board. On clicking a task from another project, I see I can allocate it to a particular sprint in a different project.
I did this, the column "Sprint" now says the proper sprint. But when I navigate to the sprint board, the task is not visible. Wondering how I can solve this.
