Congratulations on your order! I cannot comment specifically on Harvey, but I can say my experience with my orders has been the first I get access to shipping information is the day before it arrives when I get an e-mail from UPS.
There had been an official post on the forum about the tracking notification system not working right and they were working on it. I cannot find it now, maybe that means it was fixed? You may be interested in the thread, How long does it take to get your Huel order.
