When I search for: iPhone Roku Authorization Code
The top match is… this thread… Which makes me wonder if “Roku Authorization Code” was the exact wording on the phone. (Because usually if I search for some words in a thread, and search goes right back to the very same thread, then that’s either a super obscure problem or something was mistyped.)
Other than that, I can only suggest checking the phone for any Roku-related apps. I don’t think a phone itself will suddenly demand information about a Roku. I know some people try to download Roku’s app for their phone, and accidentally download someone else’s app with Roku in the name.
Banned but back. Because why not?
