Why is Console.ReadLine() not working in Code Playground?

Question

I am new to coding and new to SoloLearn. I was trying to play with console app where I want to read data entered but to no avail. The write Line prints out but that's it.
Here is my code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace SoloLearn
{
class Program
{
static void Main(string[] args)
{
Console.WriteLine("Hello World");
string data = Console.ReadLine();
Console.WriteLine(data);
}
}
}
