To follow up, the sidenotes display correctly when previewing the post. But I had not installed any new plugins or updates before things stopped working and deactivating all plugins has not deconflicted the issue. Love the plugin, it is vital to the site so any help is much appreciated.

correction, this displays:
a id=‘ref-1′ class=‘side-matter side-matter-ref’ href=”#note-1′ style=“color: #ea1717”

FYI – the issue seems to have been resolved with the WordPress SEO 1.4.15 update.

Also, unrelated note: when encountering issues with displaying the side notes in a custom theme when first using the plugin, I altered the CSS to look like the below (beginning at line 184).

ul {
  list-style: none;
  list-style-position: inside;
}
