This is just a re-hash of the grades.
I found the old analytics very useful. I could tell at a glance how students were doing, individually, not just a useless class average. Also, the refresh every 24 hours is misleading; I sometimes need real time information. So I just look at the grade book and don't bother with analytics anymore. By the way, I have checked new analytics now and then recently just to see if it has changed. Now I just get a blank page, i.e. no information at all. I will ask the local tech. about it.
