Known issue - Windows Hello is broken for NTLM flows with multiple redirects

Windows Hello auth is currently broken when authenticating to sites that have multiple redirects in Edge 81 onwards. This means that you can't access sites using NTLM flows if you don't get SSO. To work-around and access these sites, try to refresh the page while on the error page and you should be able to access these sites. We plan to patch this in an upcoming build (ideally by the end of April)
