I just bought the Nike sensor to try it. It did record my workout and everything in my iphone but when I try to upload my workout to nike+ from Safari it just keep me cycling in the login screen. Then I try it with the Chrome browser in the iphone and It worked! Is there something I can do to fix this problem in Safari???
I was having the same problem. Turn off private browsing and allow pop ups. I also cleared out any browsing data. This did the trick!!! I presume it was the pop ups as Nike loves pop ups for some reason but it could have just as easily been the private browsing.
