I'm having an issue with the Summary Widget in AppBuilder. It works fine using Summary Template with the same hosted feature service layer data I am attempting to use with the the Summary widget in AppBuilder. After configuring the widget, the title "Summary" appears but there is no data being summarized nor the names of the fields to be summarized. Is this a known issue that is being worked on? I'd really like to create a mpa that summarizes data in the viewer and also has a legend. The Summary Template does not enable me to include a legend. Any thoughts?
