I am having the same issue on my ROKU Streambar date today is 10.24.22. Everyday I have to goto the ROKU settings and turn the Closed Captioning because it keeps turning it off on it own. I have several Roku devices in the house and this is the only one that I notice does it consistently. This is my ROKU device info.
