After installing and signing in with an Orchestral Tools account (free), the
"My Licenses" tab is loaded. However, the tab contents remains blank. This
prevents downloading application content necessary to use the application.

It appears this page is implemented via an MS Edge based embedded
browser/webview, which seems to be relevant here - all pages that appear to be
web views fail similarly, but other pages work fine.
