Free this week HBO Max: No 'Hacks"

Hi, My Xfinity guide shows that HBO Max is Free this Week to stream until Sunday, June 21. When I scroll down to Hit TV shows on HBO Max, the first show listed is Hacks. However, when I click on Hacks and try to watch it, I am taken to screens that say Launch HBO Max, and that I am required to subscribe to HBO on Xfinity. How can I watch Hacks as advertised? I haven't had any problems watching other networks offered for free streaming, so I hope you can help me out. Thank you.
