Anybody know how to turn subtitles/captions on in the apple tv roku app

When the video is playing, press the up arrow on your remote to access the subtitles and audio menu.

I watch Apple TV using Roku Premiere. Here’s what I do to get subtitles/closed captions:

While the program is playing:

1. Click the down arrow on the Roku remote. This will bring up the language menu at the top of the screen.
2. Select “Subtitles”.
3. Click down again. This will drop you down to the next menu line.
4. Select “English SDH”. This will turn on English subtitles.
5. Click down again. This will remove the language menu from the screen.

I use Apple TV+ app on my TCL Roku TV. What I have found is that the default captioning is set to "English SDH" but only half the captions display with this setting. I have to hit the down arrow, then down into the subtitle menu and select "English CC" for the captioning to work properly. My big complaint is that every time I exit the app and go back in, I have to perform this same step. The app Settings don't seem to retain my selection. I don't have to do this step every time I launch other video apps (Netflix, Amazon Prime Video, Disney Channel, etc.). Apple needs to enable the option to select a CC/Subtitle setting that does not reset to the default every time the app launches. (I'm also not happy that if I pause for more than 2 or 3 minutes, it kicks me out of the video stream I'm playing and I have to resume the video and re-select my caption options.)

I discovered the same thing; the up arrow did not work but the down arrow did. I can now watch “The Morning Show” with English subtitles. Thank you!
