It's written by others. This area is a little touchy for some folk. If you feel the makers should own the app issues, vote with your wallet.

Once the app launches, the makers are not supporting the issues (so far.)
I have the UN55ES8000F with the latest firmware.
When I try to use the Samsung's own Youtube on TV app, my Smart Wireless Keyboard KBD1500 doesn't work with it.
It does work just fine with the web browser and such.
Am I missing something?
