We are having a strange problem with one of our customer. They are using SDL Web 8.5 with DXA Java 2.0. We have already installed DXA Model Service 2.2.1 however if they publish components that have links to PDF multimedia items, the PDFs are not available for 10-15 minutes after publishing the main content component. Note that the web application cache is set to 10 minutes.
Sometimes if they re-upload a different PDF (in the same multimedia component) & republish the main component the link still points to the old PDF and even on the presentation server’s file system we can see the old PDF, even if we try to manually access the new PDF’s URL.
Any idea what could be causing this or how do we troubleshoot this?
