As a magazine publisher, we receive PDF files from customers who use fonts we don't have installed on our PCs. If we open or place one of these PDFs into a document, we don't want it to replace the font as this can have unpredictable results. We need to be able to keep the integrity of the document so it looks exactly as the client intended. We can do this in InDesign, as it uses the embedded fonts within the PDF document.
The reason we switched to InDesign from Page Plus was because of this issue and it looks like it's not been sorted for Affinity Publisher.
I had big hopes for this product and would love to start using Serif over Adobe again but this seems to be one issue which you cannot resolve.
Your comments/advice would be appreciated.
