On-site messaging

Why is On-site messaging not showing on my page? | Does On-site messaging support mini-cart or pop-cart pages? | What is On-site messaging (OSM) and how do I activate it? | What kind of messaging is currently supported and where can I place it on my website? | What aspects of the message(s) can I customize? | Does Klarna display different ads for returning customers? | Is the landing page (data-key=”info-page”) a dynamic or static page? | The loading time seems to be slow, is that normal? | I’ve customized my messages but I still see the old design on my site. What should I do?
