What is happening with HBO and Xfinity (Comcast)?

Am I the only one having this problem? It first happened with the Starz App ( I could no longer sign into Starz app with my PAID Comcast subscription.) Now its happening with HBO Go on my iPad! - As of recently, I can no longer log into the HBO Go app on my iPad with my PAID HBO Comcast account. What the heck is going on? Get it together Comcast and HBO/Starz, or you guys will be losing subscriptions fast! That is, if you already havent started losing subscribers! BAD. BAD. Really BAD!
