Unfortunately, this doesn't seem to be working.</P> Mon, 21 Aug 2023 22:40:58 GMT https://community.esri.com/t5/arcgis-javascript-maps-sdk-questions/feature-reduction-across-multiple-feature-layers/m-p/1320966#M82049 AddisonShaw 2023-08-21T22:40:58Z https://community.esri.com/t5/arcgis-javascript-maps-sdk-questions/feature-reduction-across-multiple-feature-layers/m-p/1328699#M82223 <P>I ended up solving this by writing my own LayerList widget.</P> Thu, 14 Sep 2023 14:29:16 GMT https://community.esri.com/t5/arcgis-javascript-maps-sdk-questions/feature-reduction-across-multiple-feature-layers/m-p/1328699#M82223 AddisonShaw 2023-09-14T14:29:16Z
