Movement not reflecting on opponents screen

Unity Engine
1

Dear all,

I attach below script to one child object and add photon view on the child object. Every time I click the UI button, the object moves on my screen but fails to reflecting on the opponents’ screens. Does anyone knows why.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using Photon.Pun;


public class cannonMove : MonoBehaviourPun, IPunObservable
{
  
    public void shoot()
    {

        if (shootBomb.ammoAmount >= 1f)
        {


            this.GetComponent<PhotonView>().RPC("moveBack", RpcTarget.AllBuffered);


        }


    }


    [PunRPC]
    public void moveBack()
    {
        gameObject.transform.Translate(Vector3.right * 1f);
        StartCoroutine(backMove1());


    }

    IEnumerator backMove1()
    {
        yield return new WaitForSeconds(0.1f);
        gameObject.transform.Translate(Vector3.left * 1f);
    }

    public void OnPhotonSerializeView(PhotonStream stream, PhotonMessageInfo info)
    {
        throw new System.NotImplementedException();
    }
}

Should mention this is photon and which kind of photon in your title or you’re unlikely to get the right people to see your question.
