Hmmm, this made some difference, in that the song detail page now displays the NAME of the custom field if it is set, but NOT the value of that field. Also, my real goal is to be able to filter on various values of those fields on the product list page.
Let me explain better. The website is essentially a means to provide free downloads of sheet music for songs my father wrote/arranged. In the example you site, that pdf is a scan of the sheet music. That’s behaving as expected.
What I do NOT expect is a partial display of one of the uploaded pdfs on EVERY product listed. This behavior is ONLY on iPhone.
Some songs have a simple pdf which is linked as the “audio file for sale”. In the case of this song (Elegy), I initially uploaded a simple pdf as I was learning, but realized I needed to upload a zip of various versions of the song, so I linked that instead. You can see that on page 4 of the Product Page. So, all songs have a pdf or zip.
