From the Office 365 SecureScore site, I am being redirected to other company's sites.

When trying to access TLS and "Configure expiration time for external sharing links", I am being redirected to other companies' profiles (it obviously does not allow me to log in because the username within my company does not exist in theirs).  When I enter the correct company name directly into the address bar, my site is said not to be found.  I was advised to post the question here by technical support while they try to figure out what is happening.
