First unemployment deposit is late, what should I check? (Seattle)

I was laid off as an IT help-desk technician and filed right away, and I have been certifying every week. I would rather hear the honest version than the polite one. The page shows my claim as open but no payment date. Is there a step I could have missed?

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