After a successful sign-in of Citrix Director website through a common web browser (Google Chrome or Microsoft Edge), clicking any options in the left sidebar menu (e.g., "Trends", "Filters") got no responding at all.

Because the client machine is without Internet access, the web browser in-use is actually with a quite old version, which has somewhat supportability issues to JavaScript Array.at() method. When clicking on any options (like "Trends") in Citrix Director left sidebar menu, the browser console (visible in F12 DevTools mode) keeps throwing ‘TypeError’ exception "i.at is not a function", which prevents the corresponding Director page from properly rendering.

Upgrading the legacy web browser to the latest version addressed the issue.
