Published storyline course always loading
I've created a storyline 360 course, published it and uploaded the zip file onto the server. I've put it on a page using an iframe and it appears fine but once you go past the first page the loading dots are always there. I can work through the course like normal behind them and it moves quickly so it doesn't seem to actually be an error with loading. We've found this issue on chrome and internet explorer.
Any ideas why this could be happening?
