just found this guy's post at ATT same situation.

Unable to access content on directv.com or Directv app
AT&T customer no service reaches new heights. I had fiber and directv installed at my house 6 weeks ago and have spent 30+ hours on the phone with different call centers.
First, it’s important to know I’m an RC1 customer which I’ve gathered through my troubles. This is At&t’s Unified account system for wireless, directv and internet. The reason the this is important is I’ve had numerous agents insist I’m not a customer. It’s amazing to give them the serial number and receiver card number and still have Directv agents and even a supervisor tell me they can’t help me. I responded with the question “so you don’t have the ability to look and see why this receiver and card are accessing your network?” Truly incredible
After I learned of the RC1 designation, I’ve been able to say “you’ll think I’m not a customer but look in RC1 system.” Which leads to the problem that hasn’t been solved for 6 weeks.
When I try to stream online through the directv app, the system also thinks I’m not a customer. It tells me I have no channels or entitlements for any and all content. Yet I’m an XTRA package customer. Apparently this is a known issue they escalated to tier 3. I was supposed to get a call back two weeks ago three different times and an email follow-up from Tier 3. Apparently, AT&Ts technical engineers are as incompetent as their care agents as none of the follow-ups occurred. Not once. And I still can’t access any content or connect to my DVR from the app"
