Is it possible the projects were empty? Do you still have projects?
@<1523701070390366208:profile|CostlyOstrich36> Hi, I deleted non-empty projects (many tasks in them) in order to clean up metrics usage. I still have some projects with fewer tasks. The weird thing to me is that even I have deleted some projects with many tasks and waited for more than one day, the metrics usage are exactly the same (high as before).
What might be wrong?
