Maybe your gpswas activated today. I have heard that right now its not active on all the boards for following a drivers day, they must activate it to see how you run your route and to see if you are were you said you were. This is my guess.
Be aware whenever that red warning singal alerts, the center has a report on it the next day. And when you have a long drive to that last next day air stop there's no more pre-recording it to lock in the time prior to 10:30am. So don't leave the center unless your sure you can make ALL NDA's on time.Same goes for NDA Savers and 2nd day am's.
