Only TV Plus, Netflix and Prime Video are launching. All other apps in my SmartHub won't launch. When I navigate to the app, the preview shelf shows, when I click to open the app, I get the tone, but nothing happens. Hulu, HBO Now, Showtime, HGTV, Google Play, Vudu, etc.- none of them open. I've made sure to update to the latest software, I've reset both the TV back to factory settings and the SmartHub. What is happening?
