ID verification problems, anyone solved this? - what worked for you?

My claim has been on hold for 14 weeks because the identity check will not accept my documents. It has been weighing on me all week. The in-person office has long lines. What finally worked for you?

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

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