Hi Russ,
Apologies for what might be kind of a lame reply. I don't believe I can share the map for privacy reasons. I wanted to add some screenshots of what I'm talking about, but the site is telling me I don't have permission to do that, either.
The symbology was created in ArcGIS Pro before sharing as a hosted feature layer. It uses unique values for two different fields, both of which are text domains. The symbols themselves are pretty simple- polygons with 1-2 layers of solid or hatched fill plus an outline- so nothing that should break the internet or anything. In fact, they still show up on the map just fine!
In AGOL, I've created a series of maps that are all essentially regional views of this same layer. In each map, I've added a filter that only shows features within the associated region, which is a third text domain field (so I believe this would be a display filter, as opposed to a filter I set in the layer's data tab). It is when this display filter gets set that most of the legend disappears, and I am left with only the "All other values" section. If I remove the display filter, the full legend is restored, but obviously the purpose of the map is defeated.
Does that help at all?
Thank you,
Jay
