When you export your session to PDF or Word, the attachments will not be included. Therefore, choose ‘Attachments’ from the Export menu and you’ll see all the attachments to every block in your session. You can then click on the ‘Download all’ button to download a ZIP file of all these attachments.

If you have a multi-day session, then you’ll need to export the attachments on each day, as the Export > Attachments menu will only show you the attachments on each day of your agenda at a time.
