I’ve been using Nokia Transit since I got my Lumia 822 two months ago. Most of the time, it works very well, but sometimes it seems to be missing schedule data. The most consistent problem is that for some reason Transit seems to believe that the MBTA Green Line –the line I use most -- doesn’t run on Sundays. Bing and Google maps both know that it runs seven days a week. Why not Nokia Transit? It makes the app pretty much useless on Sundays, because it tries to send me on long, convoluted routes using multiple bus transfers when there’s a much better option on the Green Line.
