Review 360 Requiring Stakeholders to Create Articulate Account. Please help.

Note - I just want to clarify that these are not individuals who have had Articulate Ids/accounts in the past.  After providing the review link, respondents are being asked to provide an email (which is fine) then they being redirected to the main Articulate sign-in page where they are being asked to re-enter an email address, provide a password or sign up for an account.   I have not found a work around.  Providing a password for the Review link does not work as respondents are still being redirected to the main page and being asked to create an account.
