So if I understand it correctly, it seems that Roku actually registers the action that has produced a redirect into the browsing history, same as if you do return MainMenu() and you’re back at the original issue. I’m not aware of any standard that governs browsing history and redirects, so I guess we can’t tell whether it’s a client bug or not. But it means that redirect will not solve the issue.
You may (and should :)) certainly try these two approaches, but I think changing the title won’t take away the issue with the back button as it would still take you back to another sorting order change. Why don’t you try to return ObjectContainer(message='Boom!'), ie with a message and not truly empty, instead of return Redirect(PREFIX) or return MainMenu() and see what happens?
