Follow up to my last post. If you venture into the secret menus, be careful. I got into a menu that would display a new code for every button I pushed. None of the buttons on the remote did any of the functions they are supposed to. I couldn't exit the program no matter what I tried. I unplugged the power cord for one minute. The Roku restarted just as a normal restart (bouncing Roku ball) and everything was fine.
As for the intermittent IR problem, I have now gone for another two weeks or so without any problems. If the problem occurs again, I think I'm going to try a "hard reset" which will leave the Roku as it comes new but should keep the latest software updates. I will just need to enter all my info again.
A little back ground on me, I have four Roku Ultra's including a "model 2022" that is my main one. I've been using Roku's for a least 8 years. The intermittent IR problem is by far the worst experience I have ever had with Roku. Hopefully they will get it figured out soon. When Roku's are working properly, I much prefer them over other streaming devices, including my Apple TV 4K. Yes I am a heavy user. 😎
Thanks for the info about the secret menus. I didn't have to do that though because mine has been working for the past week. I didn't do anything differently. I believe I'm on the same firmware and software version I was when it was having issues. I'm hopeful mine will continue working - but not very confident that it will.
I think you're correct about everyone is probably on the latest updates. The fact the problem comes and goes is probably what is making it difficult for Roku. I'm pretty sure it is only the new voice remote pro remote that has the problem.
If you are still experiencing an issue with your remote, the issue you are experiencing may be unrelated to this thread. Can you please send the serial number of your Roku device from Settings>System>About to me through a PM? I'll be able to assist you further from there.
