It appears that the Geomap widgets in Google Analytics Dashboards might have a browser bug. I tried to use the widget on 2 laptops (1 windows, 1 mac) and 4 different browsers.
What happens is when you choose the geomap widget it hangs on “loading…” and this prevents you from choosing a metric. I did some research on this and found a Google Group discussion here , but there does not seem to be an answer yet.
I hope that Google fixes this soon, or at least informs users what the issue is. All other widgets work, it is only associated to the Geomap widget.
