My submission received 3/28, schedule for grading 4/2. 21 books 1 modern, rest GA Universal, standard.
I know this doesn't help you. Waiting till friday, seems prudent. But these are your books!, IDGAF what the perception would be of me, i would call them and reiterate your concern. You have (will) paid submission fees and no one can criticize you for that. You are not asking for something free.
My feeling is it will show up and i'm sure you have double checked the address sent,who signed for it, etc.
