> If you have an iPhone you can input with that, including paste.
That popping up on your phone is not 100% reliable, though, and even more hilariously, when using it with YouTube, it'll sometimes just take the first handful of characters and drop the text input box on the phone. Oh, how we laughed.
(this may be a generic Apple TV problem but it's something I've only noticed on the YouTube app)
Yes! It doesn’t work at all. This is, as I wrote, that the YouTube app on Apple TV has a custom keyboard on-screen input without any way to put actual focus on the text/password field to trigger the Remote app on the iPhone to enable input such as pasting anything.
