Hi there,

Has anyone yet played around with loading utag.js with rel="preload" and it's affects?

E.G

<link rel="preload" href="//tags.tiqcdn.com/utag/{company}/{profile}/{environment}/utag.js" as="script">
vs
<script src="//tags.tiqcdn.com/utag/{company}/{profile}/{environment}/utag.js" type="text/javascript" async=""></script>

For tealium is there any advantages of loading this way vs loading async ??
