This problem has been happening for about two months! CBS News is the only channel which I have seen cause it. It turns on closed captions for all Roku channels every time. Is someone really actively working on this problem?
Please be aware that some channel manages its own content programming, including closed captions on contents. Reach out to the channel If changing the captions on the Roku settings does not resolve the issue.
I have the same problem with CBS, but also with Sling and Amazon Prime, and all three started exactly the same time, last Saturday 2/27. I do not believe the channels have anything to do with it (why would they annoy their customers intentionally?). I did a chat with Roku support on Monday, gave them lots of info and they're supposed to get back to me today, maybe. Standing by. But since this is occurring on both my TVs (one a TCL with Roku built in, the other an old TV with a Roku Express), I'm convinced its a Roku thing, its the only common denominator.
Update - with a little observation and experimenting, I've determined that CBS News may be the culprit. When I first turn on my Roku and go straight to Sling, there are no captions, If I go to a CBS News app channel, the captions come on, and stay on even if I go back to Sling. I confirmed this by going into Settings, turning off Captions, then going to Sling - no captions. Went back to check the Settings and Captions are still off. Went back to CBS and Captions are on. went to Sling and they're on there too, then went back to Settings and they're reset back to ON. So as long as I don't watch CBS I'm OK. I know what you said about an app (network) controlling their caption settings, but how can their settings control the actions of another app?
OK you nailed it. I have Sling and Prime and just realized that captions came on only after watching the CBS app. But, as it happens, the CBS national channel is available on Sling, without the captions. So it must be the CBS app.
Hey MaryFranco - FYI, that CBS link you provide is worthless. Its not about any kind of tech support, its only for commenting on TV shows. The only Help link they have on their page goes to a dead page. I would hope someone at Roku has a way to reach out directly to CBS and report this issue, they don't seem to want to hear from their viewers, not even on their Facebook page.
I solved the problem by doing a factory reset with a paper clip and then using my Roku account to automatically reload the channels. I did this for all three of my Roku's and it fixed them all! Now I can go to CBS News and the closed captions stay off everywhere!
