We did a clean install of 13.3, and most things are working fine - except the sessions graphs. For example, Performance -> Blocking Sessions -> <click on Session ID> -> Activity tab
Get a header of "Average Active Sessions by Wait Class, and it refreshes.. but never displays the graph.
Top Activity works. Performance Hub works. Ash Analytics works. There just a couple things like the Session Activity that don't. And we use that a lot.
Anybody got any ideas? I hate to just trash it and restart from scratch hoping we don't hit the same thing.
Thanks in advance.
