When embedding the dashboard as an iframe, and selecting a segment in the segment list, the widgets refresh and only some of the widgets correctly apply the segment. It seems maybe that those widgets that load within widgets don't get passed the segment value.

All users: valid metrics

Mobile users: note the left report is correct, while the Visits overview with graph still show same data as all visits
