[SOLVED]My UI text don't update from script

Question

I have the following script

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 using UnityEngine.UI;
 using UnityEngine.SceneManagement;
 
 public class SceneFader : MonoBehaviour {
 
     public Image img;
     public AnimationCurve curve;
     private float _progress = 0f;
     public Text loadingText;
 
     private void Start()
     {
         StartCoroutine(FadeIn());
     }
 
     public void FadeTo(string scene)
     {
         StartCoroutine(FadeOut(scene));
     }
 
     IEnumerator FadeIn()
     {
         float t = 1f;
 
         while(t > 0f)
         {
             t -= Time.deltaTime;
             float a = curve.Evaluate(t);
             img.color = new Color(0f, 0f, 0f, a);
             yield return 0;
         }
     }
 
     IEnumerator FadeOut(string scene)
     {
         AsyncOperation operation = SceneManager.LoadSceneAsync(scene);
 
         operation.allowSceneActivation = false;
 
         while(_progress < 1f)
         {
             _progress = Mathf.Clamp01(operation.progress / 0.9f);
 
             loadingText.text = "Loading... " + (int)(_progress * 100f) + "%";
 
             //Debug.Log("Loading... " + (int)(_progress * 100f) + "%");
 
             yield return null;
         }
 
         float t = 0f;
 
         while (t < 1f)
         {
             t += Time.deltaTime;
             float a = curve.Evaluate(t);
             img.color = new Color(0f, 0f, 0f, a);
             loadingText.color = new Color(1f, 1f, 1f, a);
             yield return 0;
         }
 
         //SceneManager.LoadScene(scene);
         operation.allowSceneActivation = true;
     }
 }

and as the title say, the loadingText don't update to show what is in the function

It seems my text was not big enough to display all the content

How to load a scene async and display the progress:

 using System.Collections;
 using UnityEngine;
 using UnityEngine.SceneManagement;
 using UnityEngine.UI;
 
 public class AsyncOperationProgressExample : MonoBehaviour
 {
     public Text m_Text;
     public Button m_Button;
 
     void Start()
     {
         //Call the LoadButton() function when the user clicks this Button
         m_Button.onClick.AddListener(LoadButton);
     }
 
     void LoadButton()
     {
         //Start loading the Scene asynchronously and output the progress bar
         StartCoroutine(LoadScene());
     }
 
     IEnumerator LoadScene()
     {
         yield return null;
 
         //Begin to load the Scene you specify
         AsyncOperation asyncOperation = SceneManager.LoadSceneAsync("Scene3");
         //Don't let the Scene activate until you allow it to
         asyncOperation.allowSceneActivation = false;
         Debug.Log("Pro :" + asyncOperation.progress);
         //When the load is still in progress, output the Text and progress bar
         while (!asyncOperation.isDone)
         {
             //Output the current progress
             m_Text.text = "Loading progress: " + (asyncOperation.progress * 100) + "%";
 
             // Check if the load has finished
             if (asyncOperation.progress >= 0.9f)
             {
                 //Change the Text to show the Scene is ready
                 m_Text.text = "Press the space bar to continue";
                 //Wait to you press the space key to activate the Scene
                 if (Input.GetKeyDown(KeyCode.Space))
                     //Activate the Scene
                     asyncOperation.allowSceneActivation = true;
             }
 
             yield return null;
         }
     }
 }

try to put (operation.isDone == false) instead of _progress < 1f as a condition in your while loop
