The apple maps app is not working on Iphone 6 with updated OS yesterday (didn't work before that either). I have tried hard reset as well. This is not the only issue I have been having either.....comparing to my 4s that I had before. Other problems: In the past if someone texted an address I could click it and maps would open...not anymore. Siri does not understand me like she did on 4s. Several of my weather apps will not open...actually they open for about 5 seconds and then it closes and goes to home screen. I am really considering going back to my 4s.
