I tried testing my family by removing the trait Private Dwelling at my house, and actually after a few minutes the pizza arrived without a problem, and it was the cheese one too, so yes, the Private Dwelling trait does conflict with pizza deliveries.
Not sure if somebody write it here, but also happend to me if pizza deliver boy (girl) is just walking around your place - and they do it quite often. They cannot be visible on your lot or any place around what you can see from your lot. Then pizza will not be delivered. If you wait with call after delivery boy finish his walk and disappear, pizza will be delivered.
This still happens to me too! I haven't been able to order any type of pizza for (real life) years. I am learning that there are certain times you can't order via this thread, but I've had dozens of brand new saves and no one has ever gotten a pizza. Maybe 2017 was the last time I actually had one show up. Just commenting since this is still open that it is still happening in new saves, in every world I've tried (Willow Creek, Newcrest, Brindleton Bay, Windenburg, and Britechester). I've tried with Adults, Young Adults, Teens and Children. Always get the notification that the pizza is on the way and it never shows. I've even been able to order many pizzas and it never shows that one is on the way. Hope this helps!

I have ordered pizza, zoomers, and none of it is showing up. I had the private dwelling trait on my lot when I ordered it. After searching I removed it and the food still won’t show up.
