I love this app and have used it for years. It's had issues in the past, but there are unique features that keep me coming back. The app works great until Nike comes out with an "update" and breaks the whole thing. This time I can't access my account and it won't save any of my runs. I tried to log out or change some of the settings and it crashes everytime. I have uninstalled and reinstalled it multiple times and still nothing works. If it's not broke don't fix it!
