My Roku 4's closed captioning keeps turning itself on; it's annoying in the extreme. I think it mostly happens after watching the "Break" channel, but I can't swear to that. I notice there's an "always on" setting... wonder why there isn't an "always off" setting, too, since the "off" setting appears to be conditional. Has anybody else run into this, and if so, have you managed to make it go away? Thanks!!
