I have an iPhone 4s with all the latest software and iOS upgrades and Verizon wireless as my carrier. Waze has been having weird problems lately. Last week, it would not reroute when I went a different direction. Telling it to stop navigation and restart worked. This morning, I pressed my "work" destination address and it found the route, but it couldn't find *me.* What I mean is that when I was on 35 (a major highway in the US), it couldn't see that I was on that. In fact, it showed me as off-roading. It kept telling me to turn on streets that a) I couldn't turn on from said highway and b) didn't even exist in the area. At one point, it thought I was driving backwards when I was clearly going forward. I tried stopping navigation and restarting and switching the app off and restarting and that didn't work. It's cloudy outside today, but normally that doesn't make a difference with this app. Anyone else have this problem?
