For a few months BBC iPlayer has not working been working on our UE32ES5500K TV Smart Hub. If we click on the Button, it just goes to a black screen. 4OD, ITV and other services are working OK. It won't let me Uninstall the app, so I can't reinstall a new version. It says its on Version 2.02603. If I try and run it from the App Store screen, it still goes to a black screen. Any suggestions?
