I'm having major problems too, and when I look at the app's info, and go to the "set as default" thing, when I choose to have the app open supported websites, then look at the supported website list, there are inly 5, and they all have "xfinity" in the address. (The regular Cox app has only websites with "Cox" in the address.) I asked google what xfinity is, and came up with Comcast. I asked google what the relationship is between Cox and Comcast, and found that they are two separate companies, kind of like competitors, but they don't compete aside from when it comes to bidding on contracts for new construction, basically. Then after telling my friend about this, whose brother-in-law works for Cox, she sent me articles about it. In a nutshell, it's hackers and KRACK and the modem/router needing a security patch...I have to leave now for an appointment I have with Cox, so I will continue this as soon as I can, but maybe there's something you may be able to find out, in the mean time, based on this info.
