First unemployment deposit is late, what should I check? - 9 weeks in

I was laid off as a copywriter and filed right away, and I have been certifying every week. There are 7 people counting on me, so I am trying to be careful. I answered every question and uploaded my final pay stub. What would you check first?

When I finally got through, the agent said my employer had responded late. Once that cleared, back pay came in one payment.
