I've been noticing that the blue dot location marker in iOS 7 maps occasionally gets "stuck" and doesn't update it's location. This happens on my iPhone 4S and iPad 4, so far on all versions of iOS 7 (currently both devices are on 7.0.2). I can't make it happen at will, but just about every time I use Maps to navigate while driving, at some point during my drive, I will glance down at the map, and I will notice that the blue dot is "stuck" at the intersection several blocks behind me. If I then tap and slightly drag the map, the dot will quickly jump to life and snap to my correct location. I don't recall seeing this while using the 3D turn-by-turn view, but it frequently happens while either in Overview view or when viewing the map while not using turn-by-turn. Is anyone else experiencing this?
