Up until last week I was able to link Xfinity provider to the NBC, ABC and FOXNow Apps on my Toshiba FireTV and watch LIVE since I am a subscriber of Xfinity. Today I am not. I have done a forcestop; cleared cache, cleared data and tried to LINK again to Xfinity provider and now I get a white screen and it does not allow me to link in. I have removed the apps and re-installed and the same thing occurs and I cannot link to Xfinity. The videos within the NBC, ABC and FOXNow apps work. It is the LIVE TV streaming no longer works. If I try another service provider to link to, the LIVE streaming works which leads me to believe there is something wrong with Xfinity app. How can I get this to work again??
