I updated to Omeka S v.2.1.0 and the Center Row theme v.1.5.0, and now PDFs are no longer showing up embedded on item pages. (Embed media on item pages is checked in theme settings.) If I switch back to the Default theme v.1.4.1, the PDFs are still embedded on the item pages. Has anyone else encountered this issue and/or have any ideas for a fix? Thank you!
