Why is the downloaded PDF outdated? Answered
When I click on Download PDF at https://www.instructables.com/id/Spin-Art-Machine-Kit (an Instructable I created), it downloads a version of the Instructable with older photos and content. I thought perhaps there was a delay in updating the PDF but I waited a day and it still is happening.
As an example, the third page of the PDF (Step 6) shows alligator clips attached to a slide switch. But in the published/online version of the Instructable, Step 6 shows a slide switch with wire leads.
