When viewed on mobile device (iPhone and Android tablet), the audio on the first slide in a scene does not play. When I advance to the 2nd slide in the scene, then the audio plays. When go back to 1st slide from 2nd slide, then the audio plays. My .story file has 9 scenes. It was created in Storyline 360. This occurs both on Articulate Review and when published to SCORM and loaded to our LMS.
