What's the deal with empty listings? – TV Guide: Streaming & Live TV Review

I usually like TVGuide, my parents even had a subscription. It was always the first place I'd look for listings. But lately, on the app, whole channels have been empty. I'm talking ABC, NBC, & CBS, AMC, etc. major networks! I'm guessing it's the whole company because I went to their full site and it was the same thing. I give it 3 stars because if I don't need to know the blank channel, then it works fine.
