What happened? – NextTrain DC Metro - AR Review

I've been using this app for about a year and found it rather handy... Until this week. Three days in a row I've hustled for a 3minute train only to find not only no 3minute train, but no ten minute train either. Where do these guys get their data? Tired of running and disappointment.
