I did NOT update to the new DirecTV app and my "old" version stopped working the day new version was released. Now, after I enter my user/pswd the app just hangs at the authentication screen with the little spinning wheel. I am running the "paid" version of xcon which is supposed to prevent even the "you need to update" message.
The iPHONE app continues to work fine for scheduling which is what I really need.
You still need just xCon from the repo I listed above. You can upgrade to the new DirecTV app version now and all will work fine once you install both. I was having the same hanging issue as you before.
