On tv mode, the back button is not working using DirectTv universal remote
I'm trying to configure LG UJ6300 TV's remote on Directtv smart remote. Most of the buttons works fine but, the most annoying thing is the back button is not functioning at all. SO, If I switch to any app I can never for back I had to turn off the tv and reopen the app and select a new program.
Note: the back button works fine on DirectTV mode.
Can anyone help troubleshoot the issue?
