The one thing I can't recall trying is the keyboard function on the Roku app on my phone. I don't think it worked, but now I simply can't recall. And in addition to that, the channel in use on the Roku would have to recognize the number press. Since no Roku remote includes numbers, it's entirely possible they didn't program the channel to recognize a number button press on the app.
Nope, just tried the app on my Premiere, attempting to change the channel number in use in Pluto TV. No response from the channel.
