How to implement a key in the local storage with timestamp on GTM
Insert the following script into a Tag in Google Tag Manager:
<script> window.localStorage.setItem('meiroCartTimestamp', new Date().toISOString()); </script>
The tag needs to fire on the addition or removal of the item from the cart - these triggers need to be defined in Google Tag Manager.
