Assessments which have been approved as unsubstantiated were previously restricted from being accessed 180 after being approved. This restriction has been removed and these assessments now be viewed by authorized workers even after 180 has passed since approval.
In the Quick Info section of a person's profile page a yellow exclamation point still identifies these assessments and the helper text message still indicates that the assessments are restricted however this is no longer correct and this message will be removed in a future enhancement release.
