@Stealthpet you do understand that's an HBO issue, not Roku, correct? HBO is responsible for the performance of their app/channel. Frankly, their programmers are terrible. While Max plays perfectly fine on my Roku devices, I have an Nvidia Shield that cannot use it at all. It's the app, not the device, that has the issue. And HBO support seems to be worthless. I first contacted them about my Shield more than 6 months ago. I've received nothing than an occasional email telling me this new person is now my contact.
But Max does work just fine on many Roku devices. I've been binge watching Westworld again this past week, watching 2-3 episodes in a row every day. On my Ultra 4800, 4640, and Premiere 3920 (the three I used this week), Max plays fine. I wish I could explain why it's working fine for me, but I can't. Only one of the three players I listed is on the Roku beta list, so it's not that I'm running an OS version that isn't publicly available.
