Well, sort of. It seems they're using the HBONow app and if you try to login with your YouTubeTV account it points you to the HBONow activation page instead of HBOMax. The YouTube account doesn't work on HBONow. And if you go to the HBOMax activation page it tells you the activation code is invalid. Still a few kinks to work out of the system.
