Symbolize Feature Service on Two Fields in Web Map

Question

I am trying to symbolize a feature service on two different fields in a Portal web map.  The first field I choose I have all fields available.  Unfortunately, the second field I try to choose only appears to be numeric values (field list is filtered outside my control) and I want the second field to be a string field, so I am unable to symbolize the layer like I can in ArcMap or Pro.

Has anyone ever encountered this limitation?

Any ideas on how to overcome this problem if I do not have Ownership of the data and I am required to use the data as is?

As usual, I tried making things more complicated than they needed to be by using IF/AND/THEN/ELSE expressions for every possible combination. All it needed was to return one thing.

Symbolize -> Custom Expression> var VALA= $feature.A;
var VALB = $feature.B; return VALA +"-"+VALB; Select Drawing Style -> Unique Symbols All the possible combinations (up to 200) should show up. Tested and verified.

So I am only trying to use 5 different unique value combinations between two fields so I am no where near the 200 unique value limit.

A lot of the symbology options will be less refined than in desktop.  I'm not sure what you mean in your last sentence, but I don't think the issue is with any arcade expression, more the rendering options available.

For example, only 200 unique values can be categorised in AGOL (both in classic and map viewer) with only 10 colours available. Style categories (Map Viewer Classic)—ArcGIS Online Help | Documentation
