I just puzzled through finding the online files for Affinity Photo Wookbook. For what it is worth, here is what I wish had been explained more clearly.
• In the Affinity Photo Workbook, the resource file links are found at the start of each chapter.
In Chapter 2 the resource link is just above the table of contents on the chapter title page.
In many (all?) other chapters the link is in the "Before You Get Started" section.
• The links are "affin.co" They are not "affin.com". Often, I type .com automatically.
• When you click a link a web page does not open. The link downloads a zip file to your Downloads folder.
• Expand the downloaded zip file to create a folder containing the .jpg example files.
• Workbook locations for the references to the online .zip folders:
In Chapter 2, Core Skills, the example image file folder is referenced in the first step of the walkthrough instructions.
In the other Chapters, the relevant example image .zip file is is referenced in the "Before You Get Started" section.

I am using Affinity Photo 2 and have found the Book and examples very helpful (even though the book is for the original version of Affinity Photo.) It would be great if Affinity were to publish a revised version of the Workbook -- perhaps in an online-only format. Even just a supplement just demonstrating the new features of Photo would be great. The online help https://affinity.help/photo2/en-US.lproj/# is great for telling you what Affinity Photo does. But it would be helpful for Affinity to have a resource that tells you why you might want to use some feature.
