I recently tried the Fox News App, again, but it still has problems. It appears to be a different format, from a month ago, but it still freezes up in the middle of the segment. All other apps work correctly. Occasionally, when the home screen of the app comes up, it won't even allow you to "arrow down" to the segment you want to see. It sits there on a highlighted "home", and you can do nothing except close it down.
I got in contact with Fox News, but they said the problem was on the Roku end. It's a real shame no body has the expertise to fix the problem.
Looks like it's back to Pluto TV app, for my news, which is reliable.
