It's an older ATV, but it is on the latest software 12.2. I've followed all the directions to turnoff subtitles in ATV. But there persists two rows of constantly updating text in the upper left corner of the screen. I use SlingTV. I disconnected my ATV and hooked up a Roku I have. SlingTV doesn't have subtitles when using the RoKu. Any suggestions on how I can get the ATV to stop printing subtitles when I'm watching SlingTV?
