Could you tell us more about the issue you're running into? Does the problem occur on a specific channel or across other channels installed on your Roku device? If it does happen on multiple channels, please name some of it by replying to this post.
I am having the same issue, closed captioning seems to have a mind of its own. I can set it to "always off" in the main settings, the next morning it is on when watching my antenna TV channels. I can turn it back off, later when I use the Pluto TV app, it has turned itself on again. This doesn't have anything to do with a particular app, I have the same apps that I have always had. The issue suddenly showed up without any changes made on my part. There are multiple forums regarding closed captioning issues, their support team was totally useless,. Good luck everyone!
I have, multiple times. I got the same questions from the support team. They didn't work then and don't work now. The closed captioning settings on the system and apps keep switching to "Always On" without any input from me. There are tons of posts across several forums about closed captioning issues, yet the problems remain. This is not something that I or any other Roku user are missing, something is wrong, fix it.
