I have also signed in multiple times with my Verizon Fios and I cant get the Fox News App to stay connected. There is nothing to complain to Fox News about its ROKU that seems to have problem with this steaming app.
I have a Ruko TV model 43S421 not a Ruko streaming stick. I have installed the Fox News channel app and when I access the app to watch Fox News live, the program does come up but it plays what has aired and hour earlier. I have done a factory reset numerous times, uninstalled the Fox News app and reinstalled it, and have even gone through the steps of logging into the Foxnews.com/connect site and completed those steps and still when I click on the Ruko Fox News Channel app it shows live, but what comes on is what has aired an hour earlier on the Fox News channel. I cannot get Fox live using the Ruko App. I have spoken with several TCL and Ruko associates and have chatted on line as well. They were no help. I was told to contact Fox. They finally responded and said it is not a problem at their end, so it is back in Ruko Court. I will resolve the problem by moving the TCL/Ruko Tv from our exercise room to a room where my grandkids can use it to play the video games on and I will purchase another TV, BUT NOT A TCL/RUKO.
