Video won't autoplay - BUT - will play when "hamburger menu" clicked

the autoplay of the video on slide 2 cannot work

before the autoplay is enabled by the browser the user has to interact (-> click) with the html page

this is your problem trigger on slide 1

you prevent the learner from interacting with the page before the video should start automatically

• autoplay of video (with audio) is very restricted
• every browser has another strategy for allowing autoplay (Chromium, Firefox, Safari)
• storyline uses a methode, which works on all current browser -> play button with silent audio playing at start (if necessary)

here is a solution - how you can start the necessary storyline play button at the first start

or you remove the complete first slide and use instead the nice new player feature "Cover Photo fill player frame"

then the play button no longer has the "ugly" black background
