why the camera won't rotate around my object?

Question

im new to unity scripting, and now am building upon "Roll a Ball" example in unity training. I wanted to make the camera rotate around the ball in the scene in Y axis, when mouse is moved, and watched some tutorials on it, and eventually wrote the code below. but it doesn't rotate around the ball. instead it does a simple rotate in place. camera still moves with the ball though. what am i doing wrong?

public class CameraController : MonoBehaviour {

    public GameObject Player;
    private Vector3 offset;

    public float moveSpeed;
    private Vector3 point;


    void Start () {
        offset = transform.position - Player.transform.position;

        point = Player.transform.position;
        transform.LookAt(point);
    }

    void Update()
    {
        float mouseMovement = Input.GetAxis("Mouse X");

        transform.RotateAround(point, new Vector3(0f, mouseMovement, 0f) , moveSpeed * Time.deltaTime);
    }


    void LateUpdate()
    {
        transform.position = Player.transform.position + offset;

    }
}

Your problem comes from setting the position of the camera in late update. Change your LateUpdate code to something like this and remove the code from Update

 void LateUpdate()
    {
        offset = Quaternion.AngleAxis(Input.GetAxis("Mouse X") * turnSpeed, Vector3.up) * offset;
        transform.position = player.position + offset;
        transform.LookAt(player.position);
    }
