I am using ArcGIS Pro 3.3.0 and it is the first time I am trying to use and Arcade expression in a pop up. I started with the text template (seen below) that is provided and from the start it does nothing. Even the preview button in the expression screen is blank. Seems way to basic not to work. Any ideas?
return {
type : 'text',
text : 'place your text or html here'
// this property supports html tags
}
