Question
Error when exporting document produced on a Mac from a Windows
We have recently had a document produced by an external designer on a Mac, and then shared with myself (Windows user) and my colleague (Mac user).
When I try to export to PDF (Windows user) I receive the following error, but my Mac colleague does not:

This is not the first document produced by this external designer over the past several years, but it is the first time we have had this error.
