HBO Max and closed captioning

Direct TV Streaming customer here.  Yesterday I ordered HBO Max service for our home TVs.  Using a Samsung TV that is at least 4 yrs old, so as to give an idea of what equipment is being used.  Also should mention, I have a streaming tv box for both TVs.  Anyway, I use CC all the time, and it has worked on every channel flawlessly, even on regular HBO.  However, with HBO Max, it appears I have to set up CC on the settings page, specific to Max.  Okay, easy enough right?  Well, no matter how I following the prompts, I can not get CC to work on Max.  Called ATT and they said call Max, yeah right.  Went to the ATT store 5 minutes from my house, no good.  Has anyone run into a similar problem?  I need CC or I will have to remove the Max service.  Has anyone have an idea how to solve this?  Has anyone gone through the same process and had success in getting CC on HBO Max?  Would appreciate any suggestions, ideas, recommendations, and thanks in advance, cycler.
