HTML5 courses not running in Chrome
I have published different courses with Articulate 360 - HTML5 with Flash fallback (during the last year - 2017). All of them were running very well in Chrome, Edge, IE and Firefox). If I try to start a course today in Chrome, it is not running / starting (the circle just spins and spins and .................) BUT the courses are running well with other browsers.
What have I done wrong?
