My first unemployment payment still has not arrived (update)

I was laid off as a software tester and filed right away, and I have been certifying every week. This is my first time dealing with any of this. The page shows my claim as open but no payment date. Has anyone been through this? How long did it take in the end?

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