Storyline 360 and JAWS Reader

Hi everyone,

I'd really appreciate if you could give me some tips on how to make JAWS Reader work on my Storyline project.

I'm currently in the process of doing the JAWS testing and it doesn't recognise the text on the slide. It recognises the photos and the buttons and read their names but even this is quite inconsistent.

I've already put in Alt Tags and sorted out the Focus Order for everything that needs to be read. I'm not sure what I'm missing here :/
