Why PlayerPrefs not working although I use "HasKey" and Save() on android?

I know others have written this problem before but even if I use haskey or save my android device does not save data. its work fine on pc btw.

 public class PlayerData : MonoBehaviour
 {
     public float HighScore { get; set; }
   
 }

other script

 public class PlayerPersistence : MonoBehaviour
 {
    
     public static void SavePlayerHighScore(float highScore)
     {
         if (PlayerPrefs.HasKey("HighScore"))
         {
             Debug.Log("has key");
         }
         else
         {
             PlayerPrefs.SetFloat("HighScore", highScore);
             PlayerPrefs.Save();
         }
         
 
     }
 
     public static PlayerData LoadData()
     {
        
         float highScore = PlayerPrefs.GetFloat("HighScore", 0);
         PlayerPrefs.Save();
         PlayerData playerData = new PlayerData()
         {
            
             HighScore = highScore
         };
         return playerData;
     }
 }

and calling like this

 public PlayerData playerData { get; private set; }
 
   private void Awake()
     {
         playerData = PlayerPersistence.LoadData();
         HighScore();
         t.text = playerData.HighScore.ToString();
     }
