I might have been hallucinating before, but I swear that the Google Maps app would track my location with the direction of travel always at the top of the screen - the 'track up' feature for most standalone GPS units. Now when I track my location, it has me going left to right or right to left. Is there some setting that I changed? I recall several updates the past few days. Makes me wonder if that has anything to do with it. Thoughts?
