it appears to still be working on my dev system with the latest versions of everything.
NOTE… this only works on the old “Reports” page. I know that WC now has a message there trying to get you to head over to the Analytics page, saying that these reports are being replaced.
If that’s the issue, that you are trying to use the newer analytics, then we can discuss privately what it might cost to do something similar with the WC Analytics. I have not looked at their code for the Analytics yet, so I don’t know what’s possible.
If you are having some other issue on the actual Reports page, please provide more details so I can see if I can reproduce the issue here.
