I have a Tab A7 tablet and a smart tv UN40H6203AF. I installed a remote app on the tablet called TV Remote, which I found on Google Play Store. Both devices are on the same Wi-Fi. When I open the TV Remote app, it detects the smart tv and displays a single field window where I'm supposed to enter a TV Pin Code in order to pair the app with the TV. The problem I'm having is the TV doesn't display the code. The only time I ever got the tv to display the code was when I first paired it with my Microsoft Surface Book, so I know the TV at least supports this feature. If anyone has any idea why the tv won't display the code, I'd be grateful. Let me know if you need additional information.
