First unemployment deposit is late, what should I check? after 14 years as a bookkeeper

I was laid off as a bookkeeper and filed right away, and I have been certifying every week. It has been a long 24 weeks. I called the state line four times and only reached a recording. 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.

Thanks for writing this out. I went through something close to it last year, and it got easier once I kept a simple log of every call and form.
