I don’t understand HBO Max either. We already had regular HBO through Comcast. I had to go through a signup process to connect to HBO Max, but that was just a minor nuisance. Our existing subscription covers it. I can’t really tell what the fuss was about. AT&T could have just made the TimeWarner movie and tv catalogue available through regular HBO and dispensed with all the fuss of rolling out a new platform that basically overlaps the old one. It looks to me like the marketing people created an artificial problem and made everyone jump through hoops to do something simple.
Yeh, I have been using the HBOGo app on Roku but TimeWarner did away with it and is not making an app for HBOMax for Roku or Firestick but no biggie. HBO used to be the big dog for new movies and such but they have fallen way off.
