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.
HBO support for these problems is scripted, and from our experience they never ask what Roku model number is involved before proceeding with support. This is evidence that "Roku" is all the same to the support team and that the script needs serious revision.
Out of curiosity, what model, not name, of Roku player or TV do you have?
Unfortunately, this is true for the vast majority of support help lines. The people on the phone have no idea how anything works, about specific devices, or even details about their own product, outside what is within the script. They have no idea that there are Roku devices that are 12 years old, and are not supported by their service. They have no idea that their service might be available in a particular country, but that their company hasn't make their service available on Roku devices. Even sites such as Disney+ or HBO don't have accurate information about the players they support.

I did reach out to HBOMax and like others they did not seem to know enough to offer any help, beyond remove/reload app.
After reviewing the many replies to this topic, I tried the following which worked, but because I did both things I am not sure what actually worked.
Roku Ultra, connected to Marrantz Surround process, connected to LG 65" OLED. When I was first set up with HBO Max, I was able to watch WW84, but when trying to watch either Judas.. or Little Things in the last couple of days, the preview would play then when the movie was supposed to start, it just returned to the page which starts the movie.
I confirmed Roku updated. I removed the HBOMax app; powered off Roku, re-powered Roku, then Re-added HBOMax. Then I confirmed Roku recognized my display as 4k HDR and rather than set to Auto Detect, I explicitly set to the 4k HDR setting. Restarted one of the above movies and all is well.
Not sure Inteplied to the correct post...The Back door method of using "search" on the Roku main screen, out in the name of the movie you want to watch and select HBO Max, the sign in screen will pop up and voila'! The only thing's that's work for me after WEEKS of restarting, rebooting, delete, add back, and repeat!!!
I tired uninstall and reinstall. I tried rebooting Roku. I have tried everything and the app is broken. It simply does not work. Every time I start a movie it reverts to the Welcome screen. I spent an hour and a half with AT&T, and thy cannot fix it.
But at least Apple and Disney went through an experienced third party Roku Channel developer to create their apps, helping to gain insight into the fact that there ARE different code name models.
Sadly, we're informed that HBO didn't contact anyone until well after their channel release for third party support. They've had an in-house development for years, and had experience with earlier Roku channels, but these were only original earlier Android & iOS "phone apps" converted to support the Roku OS format.The starting point for the HBO Max apps was Fire OS18.104.22.168/ Android 5.1.1, both running on ARM infrastructure. Apple iOS / Vewd OS were next, with similar hardware requirements. After other OS's, Roku's 9.3 OS was last. HBO did their best to work around the channel toolbox for Roku OS, but didn't take any hardware support into account. To be fair, Roku doesn't give hardware as a component of their toolbox.
HBO is currently working with external support and are making adjustments to the HBO Max channel. They're hamstrung by the initial release and unforeseen limitations of Roku OS 9.4 in the changes to the app that they can make. We expect, at some point around the nest Roku OS release, HBO will either "dumb down" the app to match Disney+ or move to hardware restrictions like Apple TV.
