Hi Jenna,
I have just tried this with one of my courses ( I haven’t ever published for web before) and I get the same - just the loading icon but the course never loads in Chrome.
So I ran Inspector and got:
Access to XMLHttpRequest at ‘file:///C:/{folder_name_replaced_for_privacy}/course/config.json’ from origin ‘null’ has been blocked by CORS policy: Cross origin requests are only supported for protocol schemes: http, data, chrome, chrome-extension, https.
o @ player.min.js:14
and some other error - so I think it is something to do with the publishing of the course sadly - best to report this to Support a it looks like it could be a specific issue they need to address.
