MoveTowards works fine in Unity Remote but not working on build in android

Unity Engine

Hi, I have a problem when build in Android. The object don´t move but with the Unity Remote works fine and follows the player.
This is the part of the code:

Transform player;
void Awake()
{
player = GameObject.FindGameObjectWithTag(“Player”).GetComponent();
}
private void Update()
{
transform.position = Vector2.MoveTowards(transform.position, player.position, 0.03f);
}

It´s “resolved”.

For some reason, when I build the Proyect, the tag Player not identified.
I changed this code:

player = GameObject.FindGameObjectWithTag(“Player”).GetComponent();

to:
player= GameObject.Find(“Player”).GetComponent();
And now works fine.
I want to know why don´t recognize the tag Player
