You don’t need to use the neo-revive-discourse plugin for this. The solution was posted by the plugin’s author here: [PAID GIG] Help with SCRIPT Tag Rendering of Revive Ad Server Tags for Draft Plugin - #2 by neounix.
Just copy the script tag from the Zone’s Asynchronous JS tag into the head section of a theme component. For example:
<script async src="//localhost/revive/www/delivery/asyncjs.php"></script>
Then add the invocation code’s ins
element to a house ad. For example:
<ins data-revive-zoneid="3" data-revive-id="53126d71827fcba70ff68055b9a73ca1"></ins>
