My first unemployment payment still has not arrived - any advice?

I was laid off as a school bus driver and filed right away, and I have been certifying every week. It has been a long 16 weeks. I answered every question and uploaded my final pay stub. What would you check first?

Thanks for writing this out. I went through something close to it 9 months ago, and it got easier once I kept a simple log of every call and form.
