Not sure what happened, since seven days ago I'm not able to see any of the refresh information, looks like the table with the refresh info is empty; I'm able to see the query waits, query durations, datasets but in the "Refresh" page is all blank; also if I go to "Explore" in "refresh waits" A, B and D are empty. I have remove all the filters but still no info.
What else can I check?
