Consistency is a key feature of Roku, so if the BACK button absolutely must be handled by every screen, dialog, and operation in the channel why is the channel store exempt? For clarification I'm talking about the dialogs created and handled by the firmware that nobody is allowed to see - like "GetPartialUserData" and "GetUserData" has an OK button and a Cancel button but the back button is ignored. But the screen created by DoOrder() does accept the back button - it's inconsistent. Please fix it.
To investigate I looked at a few other channels - Prerequisite - remove payment method on file for Roku Billing for your Roku account
Black World Cinema - Install channel Choose premium membership Select premium for $3.99/month Select a password When it says Oops, with the roku billing dialog and Continue, instead press the BACK button Channel crashes and sits on "Please Wait" forever...
