i wrote jojo to test it on a ebook hardware device.
after that we will decide what to do.
I'm going on the the test

IMHO my accessibel file is only 1.9 MB sized, not the advertised 3.9 MB.
Looks like there went something wrong on the web here

BTW viewing in Web-Browser Addons is not the best practise known to me.
I use the Callibre Ebook Reader and my Kindle Hardware device. My Kindle comes with me, where ever I go

TIA
Jojo
