When an update is in progress (manually triggered or because they were computed more than 15 minutes ago when we open the screen) we have the message "Update in progress, please try again in a short while" (a short one which can be 1h for a large instance) but we have no idea when the data were computed previously and how many time it took which is interesting to know to have an idea when we'll have fresh/up-to-date data on the screen
