I am working on building a Web Map (using the new Map Viewer) that will feed into a Field Map. When I go to alter the feature display order in my web map, that ordering is not honored in the Field Map. Is this a known limitation of Field Maps? Or am I doing something wrong?
You're not doing anything wrong, this is a bug. I submitted this last year, no updates yet: https://support.esri.com/en/bugs/nimbus/QlVHLTAwMDE1MjIzOA==
