In ArcGIS Online, Arcade expressions in pop-ups fail to display attribute information if it is not called in a different pop-up element.

解决办法

Reference the attribute by calling the layer and then the attribute, similar to the following:

return { 

   type : 'text', 

   text : 'The 2010 Population is' + " " + $feature.POP2010 //this property supports html tags 

}
