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.
Thanks for letting us know about the issue you're experiencing.
We would recommend starting with removing the channel then re-install it back in. To ensure the process is successful, follow the steps below making sure you restart your Roku device before adding the channel again.
Remove the channel: Highlight the channel tile on your home screen and press the Star button to open the options menu. Select Remove channel and confirm.
Note: If you are removing a subscription channel billed to your Roku account, you must cancel the subscription before you see the Remove channel option. For help identifying this type of subscription channel, read the detailed article about removing a channel.
Restart your Roku device: Restart the device from the settings menu. Go to Settings > System > System restart > Restart.
Re-install the channel: After your Roku device restarts, visit the Roku Channel Store and add the channel again.
Note: If you are adding a subscription channel billed to your Roku account, you will need to resubscribe.
I can't say why some users have issues with HBO Max on their Roku devices. I use it regularly on my Ultra 4800, which of course is the latest/greatest player. However, I also tested my older Ultra 4640 yesterday to see if it behaved differently. The 4640 is getting close to 5 years old now, so far from the most powerful device Roku sells. To my surprise, it worked satisfactorily on it as well. It did have a hair of a lag when it first loaded, but played a 4K/HDR movie without issue. I last tried Max on my Nvidia Shield (a far more powerful and expensive player), and it's still completely unusable.
HBO has terrible app developers, and they don't seem to be getting any better. Unfortunately, it's HBO's problem to resolve. All Roku can do is work behind the scenes and try to get HBO to fix their channel. Just a guess on my part, but I expect that is already happening. But they have no power over them to make it happen.
