Xfinity Stream error TVAPP-00249 on Apple TV, iPad & website show only sports & odd selection of TV GO channels

While the app on the Apple TV shows all channels available, clicking any channel to stream results in TVAPP-00249 error. App on iPad or Stream website listings skip over all channels up until NBA League Pass, and then includes an oddball list of TV GO channels that do not include any channels from our actual service subscription that I know of.
