@enauticss861856 at.js 2.x does not have a global mbox request concept but rather a page-load request. A page-load request can be viewed as a request to retrieve content that should be applied on the initial page load of your website.
In at.js 2. x , you no longer see “ target-global-mbox ” visibly in the network calls. Instead, we have replaced the “ target-global-mbox ” syntax to “ execute > pageLoad ” in the JSON payload sent to the Target servers.
Essentially the global mbox concept was introduced to let Target know whether to retrieve offers and content on page-load. Thus, we have made this more explicit in our newest version.
