Calls to the SDK are all made via an array-like push method. This ensures that also calls which are made before the Script even loads are added to a queue.
Please make sure that your personal CleverPush code is implemented on every site (
<script src="https://static.cleverpush.com/channel/loader/XXXXXX.js" async></script>).
CleverPush = window.CleverPush || ; CleverPush.push(['triggerOptIn']);
