The NRC app is showing some signs of life after the January update. I was able to view my unrecorded runs (Dec 18 to Jan 22) in the All Activity tab until I was prompted to log in, at which point they disappeared. The app worked perfectly for two days until the connectivity issue reappeared. Perhaps the next update will finally fix the problem ... nope, nothing changed after the February update. My experience is that it takes Nike six months to fix its app issues (three months and counting).
