You need to press the "Up/Down arrow" button on the bottom (for me it is the 3rd from the right) and then press "Download current view".

Took me a while to figure that out as well.

For large cities I recommend only downloading small areas as the UI gets a bit laggy with a large number of things in view

I tried that, but it seems to be for downloading editable things to edit, and I can only do it for small sections at a time. I just mean seeing the streets and things, some of which load automatically as you move and zoom, and some of which don't.
