Player gets stuck on moving platform

I have this simple moving platform code but the player gets stuck on the platform only some of the time... Sometimes it works perfectly. Can anyone help? :(

     private void OnCollisionEnter2D(Collision2D collision)
     {
 
 
         if (collision.gameObject.CompareTag("Moving"))
         {
             this.transform.parent = collision.transform;
 
         }
 
         if (Input.GetButtonDown("Jump"))
         {
             this.transform.parent = null;
         }
 
 
     }
     private void OnCollisionExit2D(Collision2D collision)
     {
         if (collision.gameObject.CompareTag("Moving"))
             this.transform.parent = null;
     }
