I'm trying to setup azure devops test project and introduce it to our team. So I created test user stories and related tasks. I also created test sprints (10 work days each) starting with 2021-07-19. So far so good. Taskboard contains tasks and user stories, for test purposed I "finished" some work yesterday. Backlog tab seems to be working well, remaining work and work details works as expected too. Capacity tab is filled.
But once I enter Analytics tab with burndown trend it seems to be empty. No task nor user stories. Did I miss something? I tried all tutorials and all seems to be set correctly. See pictures below.
Do you have any advice or hints?
Thanks!
EDIT: Legacy burndown graph in dashboard works fine.
