That is quite interesting. I had a situation where a location ~20-30 miles from my current location was not updating when viewing in the app, but when I routed to it, the tiles updated and when I went to view it, the updated information was there. It could be that beyond a certain tile radius it doesn't update until you get there, so swiping through it will help it force the downloads. Unsure exactly how the app is doing it or maybe it has changed over time too.
Have you tried just viewing the Overview to see if that will download the other tiles before start your drive? or do you have to be zoomed in to a certain level?
