I've been having the same issues. Tried logging out, uninstalling and reinstalling on my 86" and every day I get a 19-2 (not subscribed) error or a "1-0" error black/Grey bar at the bottom of the screen. My only workaround is to reboot the TV by unchecking one of the user agreements on the General page until it dies again. Super annoying. I hope it gets fixed soon...
