ANOTHER Third-Party App Complaint

I switched to AT&T U-Verse from Spectrum when my Spectrum bill was raised by $50, and like many of the other complaints I've seen in this forum regarding this SAME subject, I made sure to check that I could sign into and use third-party apps on my television to watch shows with my U-Verse subscription.  Lo and behold, I have never been able to do so.  I can log in fine, but the apps all say that my subscription does not cover their network.  It does - I have U200 which covers all the channels I have apps for.  No, it's not a problem with my particular brand of tv (Roku) because I've seen other complaints here with various tv brands and types all having the same problem.  The first time I questioned it, I was told that it was a known technical issue and being worked on, and that I should have a solution within the week.  The second time, they admitted to me that it was a contract issue with the third-party networks and U-Verse, but that they hoped to have a solution again within a week.  Still nothing.  For me, it's been two months now without access to these apps, which is the main way I watch shows as I rarely have time during primetime to just watch tv.  Other users starting writing about this topic as far back as mid-2018!  I keep being told I can watch on the U-Verse app, but there are not as many shows and features as on the third-party network apps and U-Verse does not have an app for Roku, so I would be stuck at my computer or other small devices.  This is ridiculous, and if I wasn't locked into a year of AT&T I would switch back immediately.  At least Spectrum gave me the freedom to watch shows when I wanted.  I am so disappointed and starting to get angry.  When are we going to get a solution?  Don't lie to us and tell us we can access the shows on the apps when we can't, and don't lie to us and tell us a solution is near when it isn't.  Tell the truth, AT&T!  You have no solution, you're lying to your customers both before they order and when they've already paid for service, and you have no plan to compensate us for the inconvenience that this has caused to probably thousands of your customers.  FIX THIS.
