Slides do not work in browser
We are piloting the courses I am developing within my company and we often get feedback from colleagues around the world that certain slides do not work the way I built them ( the way they are supposed to work) depending on which browser is being used. My first question would be regarding this: which browser I should recommend to my learners to use? My second question is regarding two slides I built that work completely fine when I preview them as well as when I publish them in Scorm Cloud using Chrome, but do not work at all in neither IE nor Edge. However, to make things even more complicated they do no work to my colleague in Chrome either. I have attached the file containing both slides, and would like to understand if rebuilding the slide in a different way would help at all or what shall I do? I am really frustrated because I do not know what I should try to make them work after publishing.
Thank you in advance!
