I should probably describe the use case here a bit more. When the user selects a specific poster, I need to get a lot of metadata from the web before I can proceed to building the next screen. Sometimes, that can take a long time (depending on network and server conditions). So I present a "Please wait" dialog while I am getting the info.
Right now, the user is "stuck" on this dialog screen with no way to back out. I want to give them a way to cancel the request and go back to where they were.
Is there a Roku "best practice" or example around this, given that the back button does not seem to work?
