Unable to login to Max app from Direct tv stream

What happens when you login through the MAX app? Are you logging in through TV provider and DIRECTV STREAM as the TV provider option? 

Yes I am. 

how do I set up different credentials?

Did you ever get this resolved? I just switched from Uverse to Directv Stream on Monday and it won’t let me in to Max or Showtime. It just says “incorrect user ID or login” even though all of the Directv apps are working fine with those credentials. 

No I haven’t solved this issue yet. 

If you’re asking me then yes I have. I also went in to my DIRECTV account and changed the user ID and email to one that is completely unlinked to my previous AT&T accounts and that didn’t help either. It definitely seems like it is confused about the multiple AT&T accounts but I tried to solve that to no avail

Using Roku and iPad 

Yes I’ve tried all of that and just spent an hour trying different things with direct tv service tech and he couldn’t figure this out either and he’s supposed to call me back

Yea that’s the weird thing. I’ve spent 3 days trying everything. I changed the user ID and password’s multiple times. I called customer service from Max and they couldn’t help. It seems as though I was supposed to get a Max registration email from DIRECTV when I signed up and they never sent it but I’m not convinced that would even help

For 6 months I have been paying $16 for MAX as an add on through my Directv Streaming account. Worked fine until recently. Now, when I click on the blue MAX icon my programming is severely limited to only a few movies and tv shows. And anything new that I want to watch I have to go to the HBO channel 501, 502 etc. In other words I can't stream everything in the MAX library which I am paying for. Is there someway to update my MAX app using my Directv Streaming service?
