I bet anything Roku isn't even working on this issue. My guess is that they had a look at it a long time ago, found out it was a problem with the hardware in the devices and can't fix it and then just stopped responding.
They don't want to admit they screwed up and it can't be solved because then people would have the right to demand a replacement for their Roku or a refund. It doesn't benefit Roku at all to admit failure so when issues like this happen they send out their useless moderators to copy and paste stuff from the troubleshooting script that they know won't work just to give us the illusion they care, then they just stop responding altogether.
There is a similar issue with the Roku Express 4K in which the Pandora app will not work at all, it just gives you an error message each time you launch the app from the home screen, it is a known issue on that particular model, yet Roku hasn't addressed that either, they just stopped responding on that topic as well. Roku's solution is to just stop talking about it and hopefully the people complaining about these issues will forget and let it go.
I guarantee you all Roku is working on is more useless intrusive annoyances that they call 'features' to add to the software that we don't need while also working on ways to increase their ad revenue. That is all they care about.
