I just downloaded the TruTV app on my ipad and the show was available to me to watch. I have heard lots of people since then having trouble. I would suspect it got pulled because it is not supposed to debut until 1/28.
From my PC I can go to TruTV’s site too, find the show and click on it. It asks me to log into my Directv account to continue. I don’t know my password so I have not been able to go any further, but it does let me get that far which would imply I can watch it that way too.
