I have had this issue for 6-8 months and Fox News is the only channel I can't watch on my TV's that are "powered" by Roku. I have tried deleting the Fox News Channel and reinstalling it, but it still won't work. I can Stream Fox news on my laptop and my iPhone. I read one of the posts from March 5th that said they logged out of the TV provider account and logged back in, but I'm not sure how that is done. Any ideas?
I don't follow Fox News, but I remember reading this week from I believe Cord Cutters News that Fox is developing a new streaming service strictly for Fox News. While, it wouldn't explain the bugs with the app you guys have described, maybe their in the process of updating the app to include the new service. I know the article I read said they had launched a website for it, but I am not certain what the address is.
