Got this mostly working for xfinity. Only issue I'm having is that when trying to grab the Video Channel info it's coming up blank. It looks like when the link is loaded, they send an ad video. I can only assume it's to deter this from happening. Loading the link into my normal browser brings up the video immediately. When looking through the app packets before I noticed an ad in the mix too, so I'm not sure what's going on.
Maybe You can capture what link is sent by app after you put credentials. Or what is the link that guides to the screen when you put name and password
Just short info that I am trying again to make it work.
