The NRC app has not worked properly since the mid-November update. Information began disappearing from various screens (a connectivity issue) and my runs were not recorded after mid-December. The app worked for two days in January after I was prompted to log in, but then the connectivity issue reappeared. Some information has intermittently reappeared on the Run screen after the March update, but the Activity screen is pretty much inactive. The app is into its fifth month of poor performance.
