We have started the submission process and have run into a problem with the back button on Vizio remotes. The back button works as expected on Samsung Tv, Intel Development platform and in Simulator. We don't have a Vizio unit to test with and reading through the docs and forums could not find an explanation for this problem. We are using standard KONtx library and side view. Can anyone point me in the right direction?

Exact Report:
[Vizio] Back button NOT working throughout the widget
