Thanks for the information! I installed the RRemote app and it works perfectly.
Thanks to whoever suggested rremote. It seems like a great alternative to the official app so far. I did have to track down my IP manually for some reason.
It's still pretty disappointing that Roku took away the official app.
I have the same frustration. The best that I can do currently is use Windows Phone Link. I connect to my Android, and then I can open the Roku app remotely. I would love to see a dedicated Win 11 app.
