Animation Not Playing

I have been trying to set up my scenefader, but my scene fade animation is not playing. I also get another issue with the canvas / panel when transitioning to the next scene. Here's a youtube link showing the issue and my setup - https://youtu.be/sDQ_emLn4SA. I have been working on this for a week now and cannot get it to work. I wanted to add some polish to my game and therefore need to get this figured out. I would appreciate any help.

My code:

 using UnityEngine;
 using System.Collections;
 using UnityEngine.SceneManagement;
 
 
 public class SceneFader : MonoBehaviour {
 
     public static SceneFader instance;
 
     [SerializeField]
     private GameObject fadeCanvas;
 
     [SerializeField]
     private Animator fadeAnim;
 
     void Awake(){
 
         MakeASingleInstance ();
 
     }
 
     void MakeASingleInstance(){
 
         if (instance != null) {
 
             Destroy (gameObject);
 
         } else {
 
             instance = this;
             DontDestroyOnLoad (gameObject);
 
         }
 
     }
 
     IEnumerator FadeInAnimate (string levelName){
 
         fadeCanvas.SetActive (true);
         fadeAnim.Play ("FadeIn");
         yield return new WaitForSeconds (1f);
         SceneManager.LoadScene (levelName);
         FadeOut ();
 
     }
         
     IEnumerator FadeOutAnimate(){
 
         fadeAnim.Play ("FadeOut");
         yield return new WaitForSeconds (0.7f);
         fadeCanvas.SetActive (false);
 
     }
 
     public void FadeIn(string levelName){
 
         StartCoroutine (FadeInAnimate (levelName));
 
     }
 
     public void FadeOut(){
 
         StartCoroutine (FadeOutAnimate ());
 
     }
 }   

Code 2 (Using SceneFader script):

 using UnityEngine;
 using System.Collections;
 using UnityEngine .SceneManagement ;
 using UnityEngine .UI;
 
 public class ChangeSceneManager : MonoBehaviour {
 
     // Use this for initialization
     void Start () {
 
     }
 
     // Update is called once per frame
     void Update () {
 
     }
 
     public void MainMenu(){
 
         //SceneManager.LoadScene ("Title Menu");
         //SceneFader.instance.LoadLevel("Title Menu");
         SceneFader.instance.FadeIn("Title Menu");
 
     }
 
     public void HowToPlay(){
 
         SceneManager.LoadScene ("How To Play Scene");
         //SceneFader.instance.LoadLevel("How To Play Scene");
     }
 
     public void Play(){
 
         SceneFader.instance.FadeIn ("Gameplay");
         //SceneManager.LoadScene ("Gameplay");
 
 }
 
 }
