I have to ask... Why redirect US users to a StreamFab downloader (DRM MPD) that clearly fails to work with Max? From a customer service standpoint, it would be better to just display an Under Construction-type error message rather than having us log in every day to see if maybe the problem has been fixed.

StreamFab is built to recognize specific domains. If they don't recognize the domain, then it tries to find an MPD or a M3U8.
HBO Max module recognizes hbomax.com but not max.com. So when it detects a video from max.com, it tries with DRM MPD or DRM M3U8.
There is no problem to fix. They basically need to add a new module for Max. Just like when there used to be just HBO Go and then HBO Max launched. Because both were/are available simultaneously, they created a new module for HBO Max.
Logic dictates that they should create a Max module for US customers while other regions can keep using the HBO Max module.
This will 100% be in the release notes so there is no need to "keep trying" every new version if there is no mention in the release notes.
