We have a problem with Confluence's PDF Export. We are using Server v6.15.4
When we want to send a PDF copy of a page (example: report, with supporting details and JIRA issues linked), we would like to export to PDF from Confluence.
When we do, all the JIRA issues look like this:
PRJ-0001 - Getting Issue Details... Status
where we'd like to see
PRJ-0001 - Fix the thing for the guy In Process
for example...

We've been working around this by printing the web page with a "Save as PDF" printer driver, but it's not exactly what we wanted.
Anything we're doing wrong (or documented that I can't find) to resolve this issue? It seems a delay or wait between rendering for print, and exporting the PDF might resolve the issue, if we cannot trigger PDF generation on waiting on a response from all JIRA API calls.
Thoughts, Admin Settings to check and Links to open or fixed issues are welcome.
