Why did Cox delete its TV guide?

On their website, Cox used to have a pretty-good guide for TV shows. I couldn’t just scroll down through all the channels, but I could easily see the TV listing by time period for my area, identify the ones that were new shows vs repeats, and get a description. (Plus you could highlight different types, but I didn’t do that.)

But not for the last several days. Does anyone know why they dropped it? I’ve tried online customer support, but their staff doesn’t see any difference between a listing of channels and a listing of the actual shows.
