Viewing the submissions of a protected Webform

I seem to have an issue granting regular, non-admin user accounts the ability to view the results of a protected webform.

If I give a role the 'Access all webform results' permission, they cannot view the results and get a message "You are not authorized to access this page." This even occurs if they go to the webform node in question and enter its password, then access the 'Results' tab.

They can access the results of no-protected webforms.

I tried granting other permissions, except full admin ones, with no success...

Should it be relevant, I am using Webform 7.x-3.18.

Nevermind, I now see the "access protected content' and "bypass password protection' checkboxes...

Thanks,
Eric
