Our AOS (for K1) was filed and delivered via USPS to the PO BOX in Chicago on the 18th of Nov at 3pm.
We still haven't received any messages, mails, and my credit card has not been charged yet (no attempt either?).
I know Thanksgiving happened between this time so maybe that is the reason, but a bit worried as I chose to use my credit card which may not have been able to be used...
