Browser Screen Flashes Between Slides

Hey Ashley,

thanks for your reply, I really appreciate this. I quickly tested your Review link and the white flash appears between slides the same as in my testing list from previous post. (I'm attaching a short screen recording while testing on Safari - MAC).

I'm also attaching .story file for you to test (this is not the original file but the same thing happens here as well). You can see it on this Review link also.

I have tested LMS export and white flash appears as per my first testing results. Our internet speed is very good so it's not a slow connection\loading issue.

I have flash disabled in all my browser for testing purposes so I'm sure I'm looking at  HTML5 versions of all exports. 

Hope this helps us all :)

Thanks.

Marina
