Facebook Share not found

I am trying to share to Facebook but without success so far. I created 2 method just to test. The first one (Share), actually shares, however it does not grab the image or any of the text. It's just a NOT FOUND link, which redirects to the URL of the game in playstore.

The second method (Share2) does not work. When I click the button that calls it, the screen blinks really fast, and that's it. Nothing happens.

Here's the code:

 using UnityEngine;
 using Facebook.Unity;
 
 public class FacebookManager : MonoBehaviour {
 
     void Awake()
     {
         if (!FB.IsInitialized)
         {
             FB.Init(InitCallback);
         }
         else
         {
             FB.ActivateApp();
         }
     }
 
     private void InitCallback()
     {
         if (FB.IsInitialized)
         {
             FB.ActivateApp();
         }
         else
         {
             Debug.Log("Failed to Initialize the Facebook SDK");
         }
     }
 
 
     public void Share()
     {
         FB.ShareLink(
             contentURL: new System.Uri("http://play.google.com/store/apps/details?id=com.Amazing.Color&hl=en"), contentTitle: "I scored points in the game!",
             contentDescription: "i did pretty good",
             photoURL: new System.Uri("https://i.imgur.com/gwx1Fta.png"));
     }
 
     public void Share2()
     {
         FB.FeedShare("the told is here",
             new System.Uri("http://play.google.com/store/apps/details?id=com.Amazing.Color&hl=en"),
             "Link Name is here!", "this is the link caption!", "and here the description",
             new System.Uri("https://i.imgur.com/gwx1Fta.png"), "this is the media source");
     }
 }
