Norton Identity Safe URL being diverted to Norton Account Login Page

I read that a user can key in…
“https://identitysafe.norton.com/home”
…in the browser’s main text box to go directly to a log-in screen at Norton Identity Safe.

But when I enter that URL into the main text box, instantly I arive at…

“https://login.norton.com/sso/idp/SAML2?SigAlg=http%3A%2F%2Fwww.w3.org%2F2001%2F04%2Fxmldsig-more%23rsa-sha256&locale=en&SAMLRequest=rVNdj9owEPwrkR%2F6diQESA8foaJcP066Vgi4PvQFOc6Gs%2BSsXa9zpf%2B%2BTgCBTlUqVZX8YK3HOzM7 9oxErVPLF41%2FxjX8aIB8dKg1Ej%2Be5KxxyI0gRRxFDcS95JvFl0eeDhJunfFGGs2iBRE4rwwuDVJT g9uAe1ESntaPOXv23hKPY1UCeuV%2FkahggMZ5gwNp6pjIxNrsFb4rFVktcJ8rMiP%2B4eunN6K2d13V SKHhWH%2FaLFh0H6QqFC3nhaHr8rq1Km3cSk5Z9NE4CZ3ZnFVCE7Do4T5nu9Ewe1sMs%2Bq2qqa302Q8 mcqiyKZF2EqRjScBRitBpF7gcpGogQckL9DnLE2G2U0S1mibDPlowsfjwSRNvrNodRrSe4WlCtZ6 J1ocQcQ%2Fb7ermzWUyoH0LPoGjjqnAcTmsy4c3ilw13n1NxfnkNj8b5HM4muKE6HlpycCZTfDkLWH g4%2BWprbChWiCPjiIoPes8Bq21IF%2FDdU%2F6e2FSS7b3qHcZvTTuLKdeZgblFsnkGzwdTb0J0X%2FXW3v c2xb7cKFXfg9ldIQoyG1x8b2S4z7IrgcX%2F%2Fk%2BW8%3D&Signature=ftD7ZcBo9RqChU2jY%2BFiVp2Fbki%2BKsv%2FTH8rMyTqaG0bpsWmQ3IS5e8zerYdp6AKgKlGr7XAwUVa 02FGoE0vQuQIRVqAkTdZfDn0mXqP3xk7Q7u2nAikrmlJSIimaUXNuvc6CMn%2Byaz8KjSwmzrW2fr2 lTGVu7yLUNizsuiOVb5eiLwjJZKbeoaeOm3umTSVOcCve9NspYtyCby2lUCXZTOGz3D9z%2BlHPIEE mTqHulshFlk4tDcahPQw9HPowUZCwqulstORIWa4ko%2Bgtg%2FstBOYcPr5uLEJDFAdmunZ0cPGGGFF Fv0JjhxxfnQqKR3bMZnxLEKKgHmW3Yg0rYqB%2BA%3D%3D”

Why can’t I just go straight to the Identity Safe login, without having to sign in to the Norton Account page???
Thanks.
