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?
