I would expect the MiniTOC links to be active in my PDF, as with the TOC and just about all other placed links.
Is anyone else able to produce working MiniTOC hyperlinks in PDF?
They work fine by me....
Did you check the reference page?
I've never had an issue with it. You do need to select the option to Generate Acrobat data when you print the PDF.
Even more important than your excellent suggestion (which applies to Print to PDF, but not the Publish pod workflow):
Make sure you click Create Hypertext Links in the MTOC setup!!
Sometimes it's the smallest things!
