Contour 2 App - ipad, iOS 9.3.2

yesterday, I had all of my channels available on Contour 2. Today, a bunch of channels are missing, generally those between 17 and 93, except for 48 which is present. The missing channels are also missing in the 1000 channel number range. Restarting the ipad did not clear the problem. The "missing" channels are available through my various cable boxes, however.
