Replace GA with GTM

Remove all Google Analytics Code:

Paste this code as high in the of the page as possible:

```

(function(w,d,s,l,i){w[l]=w[l]||[];w[l].push({'gtm.start':
new Date().getTime(),event:'gtm.js'});var f=d.getElementsByTagName(s)[0],
j=d.createElement(s),dl=l!='dataLayer'?'&l='+l:'';j.async=true;j.src=
'https://www.googletagmanager.com/gtm.js?id='+i+dl;f.parentNode.insertBefore(j,f);
})(window,document,'script','dataLayer','GTM-MP56VBJ');

```

Paste this code immediately after the opening tag:

```

```

Inspect the site layout or template that produces the page head and opening body tag; the issue does not name a file. Find and remove the existing Google Analytics code, then add the supplied Google Tag Manager snippets in their specified locations. Verify the generated page contains the GTM script in the head and the noscript iframe immediately after body opens.
