Says EPUB3 in his post, but could be Dabcar's accidentally using this markup in an EPUB2 book.

Do you use Sigil? If you open the book in Sigil, the titlebar has a little line that says if your book is 3 or 2:



or if you run epubcheck, one of the first lines should tell you whether it's checking in epub2 or epub3 mode.

epub:type="endnote" and "endnotes" are both perfectly valid according to the EPUB3 specs:

along with "footnote" and "footnotes".

... so something else here may be causing the trouble.

(Can I ask where you got this code suggestion from?)

From what you're showing, the code does seem to look "okay".

I probably wouldn't use a giant <ul> though.

To be safe, I would wrap each note in an <aside> and use <p>, so something along these lines may work better:

<aside epub:type="endnotes">
<h2>Notes</h2>
	<aside id="fn1" epub:type="endnote">
		<p class="note"><a href="#ftn1">[1]</a> This is text for endnote 1.</p>
	</aside>
</aside>

See Doitsu's EPUB3 footnotes test-case from 2016 (not much has changed since then).

That would more gracefully fallback, and work a bit better across a variety of readers.
