ArcGIS Online Labels with Arcade Custom Expression Won't Render in App

I'm trying to label address points (with the ArcGIS Online labeling functionality) for one of our city's webmaps. Some of the addresses have unit numbers, some don't. I put together an Arcade expression that checks the "unit" field for values so that all points will be labeled correctly.


var unitVal = $feature.unit
var stVal = $feature.snumber
function mainfunc(unitVal,stVal){
  if (unitVal == ' '){
      return stVal
  else {
      return Concatenate([stVal,unitVal], ':')



The labels appear correctly in ArcGIS Online, but will not draw in a web application that calls on that AGO map. Has anyone come across the same issue?
