Objects' movements aren't synchronized perfectly

Hi, I have the following problem with physics in Unity Netcode.

Suppose that one client starts moving his object (using rigidbody2d.Addforce). However, another client observes this movement ~0.5-1 seconds later than this object actually moves. How to solve this problem with time delay (P.S. I'm relatively new in unity coding)?

public enum State { up, down, left, right, no }
State realstate = State.no;
float speed = 70f;
void Update()
{
if (IsLocalPlayer)
{

{
if (Input.GetKeyDown(KeyCode.W))
{
realstate = State.up;
}
if (Input.GetKeyDown(KeyCode.S))
{
realstate = State.down;
}
if (Input.GetKeyDown(KeyCode.D))
{
realstate = State.right;
}
if (Input.GetKeyDown(KeyCode.A))
{
realstate = State.left;
}
if (Input.GetKeyUp(KeyCode.W) || Input.GetKeyUp(KeyCode.S) || Input.GetKeyUp(KeyCode.D) || Input.GetKeyUp(KeyCode.A))
{
realstate = State.no;
}
}
}
}
void FixedUpdate()
{
if (GetComponent<Rigidbody2D>().velocity.magnitude == 0)
{
if (realstate == State.up)
{
transform.localRotation = Quaternion.Euler(0, 0, 0);
GetComponent<Rigidbody2D>().AddForce(transform.up * speed, ForceMode2D.Force);
}
if (realstate == State.down)
{
transform.localRotation = Quaternion.Euler(0, 0, 180);
GetComponent<Rigidbody2D>().AddForce(transform.up * speed, ForceMode2D.Force);
}
if (realstate == State.right)
{
transform.localRotation = Quaternion.Euler(0, 0, 270);
GetComponent<Rigidbody2D>().AddForce(transform.up * speed, ForceMode2D.Force);
}
if (realstate == State.left)
{
transform.localRotation = Quaternion.Euler(0, 0, 90);
GetComponent<Rigidbody2D>().AddForce(transform.up * speed, ForceMode2D.Force);
}

}
else
{
if (realstate == State.no)
{
GetComponent<Rigidbody2D>().Sleep();
}
}
}
