My apps are not working on my Roku TV. Connections are great, apps are installed. When I click on an app, I get the apps initial logo screen, then a blank screen, then it takes me back to the home screen. I tried deleting an app, then adding it back. When I try to add it back, it says the app is already installed. I tried a System Restart about 20 mins ago. I'm getting the message "Restarting..." but the circle spins and spins and goes nowhere. Roku needs to fix this.
