On second thought, you are probably right! I’ve been looking into how to grab the info from 1 and 2 from the APIs; There is a way of finding out via the UI, though! When you go to the Metrics tab, you can open a metric and check on which Visualizations it is being used. The same goes for Visualizations - opening them in the Analytical Designer allows you to check on which Dashboards they are being used.
I understand checking them manually, one by one, is quite a bit of work. I’m checking to see if there’s a more “humane” solution available! 🙂
