Help & troubleshooting for channels on your Roku device, including adding/removing channels, logging in to, authenticating, or activating a channel, channel-specific playback issues, assistance contacting channel publishers to report issues, and adjusting channel-specific settings.
@DragonBlade Unfortunately, HBO is the only entity that can resolve this. They have terrible developers for their app on multiple platforms. The problem isn't specific to Roku devices. In fact, Max works far better on my Roku Ultra than it does on my (more powerful and expensive) Nvidia Shield. It's almost unusable on the Shield. But HBO is who has to resolve the problems.
I just tried Max on my Premiere, which isn't as powerful as your Ultra, and I could play a movie without a problem. The UI was a little laggy, but nothing like my Shield.
