I've got a layer of code violations with several date fields. Many of these date fields are used successfully in indicator and chart filters, as well as filtered correctly with a date selector in the header of the dashboard.
One date field, however, is treated as a Coded String in all widget filters except for the date selector in the header, preventing me from using any meaningful date filtering using that field. This field is correctly formatted as a date in the original desktop layer and the hosted feature service.
What could be causing this?
