Has anyone managed to figure out how to use the new HBO Max from a premier using xfinity? I have the old HBO GO app, which changed its name to just HBO recently and it seems to go to the old hbogo site, not HBO Max. It asks the old way of logging in... giving a code which must be entered at hbogo.com/tvsignin but xfinity no longer shows up in the list of providers. I signed up to HBO Max at Xfinity and can access it there from my pc, but I want to access it from my Tivo. So does TIVO have an HBO Max app?
