Sweet ride and congrats on the positive experience! Also, I didn't realize people still used checks. I'm going to go dig out my old check book and get ready for when my Bronco arrives!
I ordered in December (no reservation) and did get an email. Also I don't see my order on the Ford site either. Banner mentions you need to enter a VIN to add it, which I don't have yet.
I ordered a 2-door 2.7 towards the end of December and it appears to have gone through. I did receive a confirmation email from Ford. I have heard others say the above though, so may be for particular regions/dealerships, although I can't think of why that would be.
OP I would suggest asking...
I've ordered two builds with 2.7 and hardtop this month, the most recent 2 days ago. Maybe depends on region and/or dealership, but doesn't appear to be an across the board constraint by Ford
