Contour app

The last few days the contour app will not play channels 53,54,55,56 or 57. I'm in Fairfax County Va. I've tried on my laptop, tablet and brand new Android cell phone. I've even uninstalled the app and reinstalled it. I've rebooted the modem and router several times. I chatted with Cox and they said there was a problem with the app but didn't know when it would be fixed. Oh.... I've tried multiple other channels and they stream perfectly fine. Any idea as to when this will be fixed ? Thanks.
