Downloaded the app to iPad before first race this year and it has worked great ever since. Early this week I tried to go back to view previous races and when you click on the app it opens to the screen that is all black with the NBC logo in the center and then goes nowhere from there. I deleted the app and re-loaded it and it is the same. Anyone know why this is? Trying to get it fixed quick so I can watch races today. Any help is appreciated.
