Why doesn't Maps show my street even though it knows where my house number is?

When I put my address into Maps, the app puts a pin in the right place, but in standard view it doesn't show the street the house is located on, or the other streets in the development, which is over a year old, and it can't give me navigation directions to the house, only to the closest point on a nearby street in an older development. How does it know where to put the pin if it doesn't know about the street? Even stranger, in hybrid view, it shows not only a recent enough satellite photo that the streets of the development are visible (though no houses yet), but the lines showing the streets are there too! Go back to standard view and the streets disappear! But the pin showing the location of my lot is right there throughout. How can one function of the app know where to put the pin while another part doesn't even where the **** street is? And why does any part of the app, which presumably has online access to up-to-the-minute databases, not know about a subdivision that's existed for over a year?
