ID verification problems, anyone solved this? - any advice?

My claim has been on hold for 12 weeks because the identity check will not accept my documents. I am in Milwaukee, in case local advice matters. The in-person office has long lines. Do I need an appointment?

Check the list of accepted documents on the official site. Mine included things I did not expect, like a passport card.

Write down the date and reference number each time you try. They asked for it when I finally got through.
