Tasks are created and closed, but nothing is displayed (not only in this test Workspace but in all other I have created so far). I may be doing something wrong with the tasks, but the Workspace Insights are not being displayed either (despite I create and edit many pages; again, in all my WSs)
I am starting to believe this may be due to some licence conditions.
I am increasingly certain I am seeing basically the same thing as you are. I am confident it is not licensing-related.
I am able to get tasks to show up on the Status page. Sometimes. But I have no earthly idea what I did to get them on there. When I create my tasks, nothing shows up. If I assign/unassign them to/from myself, mark/unmark them complete... nothing. But sometimes I change tabs, then come back a few minutes later, and the task now shows up. But of course, if I were to then mark it as complete, the status page becomes out of date again...
As it stands, the Status page is worse than useless. I would much rather have no summary than all than an out-of-date summary.
