Why is the renderAS = "advanced_pdf" not working ?
Trying to apply SDLS to existing classic visualforce page.
This page is renderedAs a 'PDF'. If I add renderAS = "advanced_pdf" the page
looks exactly like the old classic page, if i remove the renderAS tag, it displays with the lightning look.
<apex:page controller="ControllerNew" renderAs="advanced_pdf" language="{!language}" applyBodyTag="false" showHeader="false" sidebar="false" standardStylesheets="false">
<div class="slds">
<body>
.......
</div>
</apex>
