ArcGIS Enterprise 11.5: Subtype group layer in webmap symbology scaling issues

Software: ArcGIS Pro 3.5.4, ArcGIS Enterprise 11.5

Goal: To create a Web Map based on a Utility Network Feature Layer. In the Web Map I want to use Subtype Group Layers.

Hi All,

I'm facing these issues, open to suggestions 🙂

Adding a subtype group layer is not possible in the web map UI on the browser. Not a big issue but would be nice if that feature is supported in the future.
Adding a subtype group layer via ArcGIS pro and sharing the map as web map is possible. However, the symbology can't be edited afterwards in the browser.
Setting the symbology within ArcGIS Pro is also possible but it seems that it is not possible to scale symbology based on current scale. I've tried the following methods:
1. setting the size by a field expression. Example of expression
  var scale = $view.scale;
  if (scale < 100) {
  return 12; // Max size when zoomed in, smaller than before
  } else if (scale < 250) {
  return 11;
  } else if (scale < 500) {
  return 10;
  } else if (scale < 1000) {
  return 9;
  } else if (scale < 1500) {
  return 8;
  } else if (scale < 2000) {
  return 7;
  } else if (scale < 2500) {
  return 6;
  } else if (scale < 3000) {
  return 5;
  } else if (scale < 10000) {
  return 4;
  } else {
  return 3; // Smallest size when zoomed out
  }
  
  Result: Orange styling in the web map (is this some kind of error?)
2. Tried scale based sizing within the symbol
  Result: No orange symbology anymore but no difference when zooming in or out in the web map.
3. Tried the scales option within the Unique Values screen
  
  Result: Same as method 2

As of now i don't have any other methods of setting the symbology scale for web maps based on group type layers. Normally you would be able to 'fix' whatever goes broken when deploying a web map via ArcGIS Pro but that seems not possible for subtype group layers.

Also tinkered a little bit with setting the subtype group layer on the feature layer level as the symbology there seems more stable/better. However, creating the subtype group layer there results in losing all domain translations for all fields :'(
