When in the Disney plus app begin playing something then click the * then go down to accessibility & captions from here scroll to audio track, if you scroll up there is a second English option. One English option (above it when you go to select) says 4 of 26 (English, AAC, Stereo), and the other says 5 of 26 (English [audio description] English, AAC, Stereo, descriptive). Whether or not you want audio description will depend on what you choose.
I have done this but once the movie is over then it goes back to the original settings with AD and I just want normal movies without the AD or having to go into settings for each movie and change it everytime. How can I do that?
