In Data presentation, when the setting "use latest data" is checked, it's not possible to use the data preview chart properly. In particular time period is not responsive. Since the chart in iLibrary can't show latest data, we need to configure start and end date even if "use latest data" is selected as default for the data portal. To choose meaningful start and end date, we need the data preview chart.
Another issue is with the subject/measure control which are not working anymore. Similarly, switching between chart/bar/map/tables is not possible anymore.
