Unable to load SOIL layer from Living Atlas in QML

Question

Hello all. Has anyone been able to successfully load the "USA Soils Map Units" layer from Living Atlas in QML?  For reference, here is the link...

https://www.arcgis.com/home/item.html?id=06e5fd61bdb6453fb16534c676e1c9b9

I am using my organization's arcgis online portal and my account, but for whatever reason when I try to load any Living Atlas layer that has a service endpoint from landscape11.arcgis.com, the layer's status goes to Enums.LoadStatusLoaded, but it never renders on the map.  If I try any of the other Living Atlas layers that have service endpoints referencing services.arcgis.com, they load and render fine.

Oddly enough if I click on "Open in Map Viewer" from my org's online portal it loads fine in the browser based map viewer.

I have attached a sample of my QML.  I am on a Mac with Qt 5.15.6 running runtime 100.10.  I did copy my main.qml to a Win machine and same result.

@JeremyRoberts2 I looked into this a bit and that layer should be working for you. I have logged a bug in internal bug tracker and we will look into this. Thank you for letting us know about this.

Hello.  I went ahead and added in something like the following in MapView...

onLayerViewStateChanged: {

console.log("LAYER NAME: "+layer.name);
   var stateFlag = layerViewState.statusFlags;
   if (stateFlag == Enums.LayerViewStatusActive)
      console.log("layerViewState Active");
   if (stateFlag == Enums.LayerViewStatusNotVisible)
      console.log("layerViewState Not Visible");
   if (stateFlag == Enums.LayerViewStatusOutOfScale)
      console.log("layerViewState Out of scale");
   if (stateFlag == Enums.LayerViewStatusLoading)
      console.log("layerViewState Loading");
   if (stateFlag == Enums.LayerViewStatusError)
      console.log("layerViewState Error");
}

This resulted in...

qml: LAYER NAME: USA Soils Map Units
qml: layerViewState Not Visible
qml: LAYER NAME: USA Soils Map Units
qml: layerViewState Active

So seems like the end result is that it is "Active".  I also checked map.operationalLayers.get(0).visible and it is "true".

Thanks for the feedback!  I'm still baffled and don't know why it isn't visible.

Do you find anything reported by MapView.Layer.layerViewStateChanged?
