Autoplay of Video in Rise/Storyline

Hi, I set a video to autoplay for a storyline scene with the workaround suggested by Articulate (adding a cover picture for the first slide). In the storyline preview, the video did autoplay with all the triggers. However, after publishing it in preview 360 and embedding into Rise, the autoplay does not work and it does not jump to the slide with the video at all. Instead, the storyline interaction only shows the cover page. Is there an issue with Storyline or is the autoplay limited in that sense? I would like the "Play" button to be removed when embedding it into a Rise block (like any other Storyline interaction) Other tips are greatly appreciated. Thanks!
