Embedded/linked PDF behaviour in Obsidian Publish notes in iOS Safari

For notes with embedded PDFs, published using Obsidian Publish:

On Mac/Safari and Windows/Chrome, multi-page PDFs can be scrolled/paged using the embedded viewer.

On iOS/iPadOS/Safari, only the first page of the PDF appears.

Is there a way to make embedded/linked PDFs behave properly when viewing an Obsidian Publish note in iOS or iPadOS?

Any help much appreciated.

Steve.

Been doing some more investigating and PDF seems totally broken on Publish sites in Safari on iOS/iPadOS. Has anyone got this working?
