Hello Jollysharon26,
Thank you for using the Apple Support Communities. As we understand it, your language settings are showing UK English, but all of the content from Apple TV+ appears to be in Spanish. Is that right?
As a test, from your iPhone, try the steps below; are you able to manually change the language settings? Change the closed captions or language for movies and TV shows in the Apple TV app
If the video you're watching includes CC, SDH, AD, or alternative audio languages, your media player should offer a way to use these accessibility features, most often through the Audio & Subtitles menu, often indicated with the speech bubble icon .
Other apps or web-based media players might show a CC button or other custom controls.
- While watching a movie, tap the screen to open the playback controls.
- Tap the speech bubble icon .
- Choose the language or subtitles that you want to use.
If you don't see an option for SDH, or you want to turn on CC or SDH by default, go to Settings > Accessibility. Scroll to the Hearing section and tap Subtitles & Captioning. Tap Closed Captions + SDH to turn it on. If you want to customize captions or subtitles, tap Style, then choose from the options.
To choose the audio languages that are downloaded with your videos, open the Settings app, scroll down and tap TV, then tap Languages. Tap Add Language and choose the languages that you want to add."
It might also be a good idea to double-check the Settings as described above if you haven't tried that already.
Let us know what you find, and whether you're able to manually change languages while playing content. That will let us know more about what might be happening.
Take care.
