Still haven’t received Maryland state tax refund after getting federal — should I be worried?

Hi, I filed my taxes through an accountant on Feb 20. I received my federal refund on March 20, but my Maryland state refund still hasn’t arrived.

I checked the Maryland refund status tool and it still shows processing / no clear update.

Is this normal delay for Maryland, or should I be concerned? Has anyone experienced a similar timeline?

Thanks.
