Same here on Chome. (I managed to get in using Safari after lots of refreshing though). On Chrome I'm seeing this error;
Refused to execute script from 'https://appstoreconnect.apple.com/access/static/js/main.b7dc51f4.js' because its MIME type ('text/html') is not executable, and strict MIME type checking is enabled
Hope that helps :)
