Perhaps the fax-related expenses would be the magic ticket their boss needed to justify security scanning of emails with PDFs. I just listened to Trump brag for ten minutes about replacing the thousand-dollar signing pens.
The post is tagged non-fiction, but it ignores the option to "Complete your Disabilty Update Report Online (https://www.ssa.gov/ssi/text-cdrs-ussi.htm), which I found after following the link in the first sentence.
The form is an embedded iFrame from "Adobe Acrobat Sign", supposedly pure Javascript . It would be a bigger story if this form were not accessible to the disabled.
The form includes a place to attach two PDF, text, or image formats. "Attachments are limited to 5MB and 25 pages".
A couple of possibilities spring to mind. Likelier that Karen lied, but maybe the 512 page fax changed the system.
