Alt Text problems
I built a quiz template using Storyline 3, and I need to ensure it's accessible to screen readers. I tested the course, and although I added alt text to all images, it's the image name (file name) that screen readers read out instead. I've tested with NVDA and Mac's VoiceOver, and both read out file names.
I changed alt text, as well as tab order, and technically the readers should pick up the newly identified descriptions. But they don't.
You can preview the quiz template here. The problematic slide - Slide 2.

Will look forward to your ideas.
