Does anybody knows why font shadow doesn’t work?

This 3 lines of code to implement font shadow doesn’t work. Does anybody knows why?

title.shadowColor = Color.black();
title.shadowOffset = new Point(1,1);
title.shadowRadius = 1;


// Variables used by Scriptable.
// These must be at the very top of the file. Do not edit.
// icon-color: red; icon-glyph: calendar-alt;

// Adapted from calendar widget created by Max Zeryck @mzeryck

// Store current datetime
const date = new Date()

// If we're running the script normally, go to the Calendar.
if (!config.runsInWidget) {
 
// Otherwise, create the widget.  
} else {

 let widget = new ListWidget()
 widget.backgroundColor = new Color("2980B9")

let title = widget.addText("IVU");
title.font = Font.semiboldSystemFont(84);
title.textColor  = Color.white();
title.shadowColor = Color.black();
title.shadowOffset = new Point(1,1);
title.shadowRadius = 1;

let sub = widget.addText("Sales Tax");
sub.font = Font.semiboldSystemFont(42);
sub.textColor  = Color.yellow();

 // Finalize widget settings
 widget.setPadding(16,16,16,0)
 widget.spacing = -3
 
 Script.setWidget(widget)
 widget.presentSmall()
 Script.complete() 
}


// Your code begins from this line

console.log("Hello world!");

Output is:

I us the same problem — @marco79 came to the rescue in this thread, with a good example of how it works:

Widget text and shadows

(Edited: Gave credit to the wrong person at first. Sorry!)

I don’t know why, but yesterday doesn’t work and today it worked. May be need a refresh somewhere. Same code.

Thanks to tf2 and Marco for your support.
