I published course in storyline 2 selecting all the appropriate selection boxes for viewing the course on mobile. I sent the same zip folder to my android mobile. I downloaded an articulate mobile player from the play store. I unzipped the folder and clicked on the story.html, It's not working. When I'm clicking on amp.html, I'm directed to amp then popup is appearing saying that one or two files are not downloaded. Can you help with the issue?
