Like i said, "You'll need to give specific, detailed example."
Roku does not need to specifically support "Tokenization CDN URL" - that's just a URL with a query string, which work just fine with Roku, thankyouverymuch. If your specific case does not work, there is something broken there - maybe there is a redirect (or two, or three). Sniff your traffic and see. For help here, provide specific example URL that does not work. Yes, if you need help maybe you'll have to create one that's shareable to the world. Otherwise it's like phoning a random hospital and asking "why do i have a headache?" 🙂
