I use symbols for the headers, footers and other common elements in a project with ~40 mockups.
With 3.0.7 when I export all the all of the mockups to pdf, all of the symbols appear as “Symbol not found”.
All of the symbols appear when I am editing the mockups within Balsamiq 3.0.7 and they also appear correctly when i use the Full screen presentation.
This function worked just fine in all previous versions I have used (3.0.3, 3.0.5, 2.2, etc.)
This is Critical functionality for me, as I post the wireframes as a linked pdf for team members to use.
