pictures goes light and dark when watching apple tv . How do I get help to fix this.

Hello jjsav133,

We understand that you're having some trouble with the brightness on your Apple TV+ app. Could you check the Light Sensitivity feature for us? Here's where to look:

Also, does this occur with everything you watch through the Apple TV+ app, or only certain content?

Thanks!

Thanks for those details jjsav133,

As this is only with the Apple TV application, we would recommend deleting the app and reinstalling it. Let us know if the problem persists after.

Thanks for giving that a try, jjsav133,

At this stage, we would recommend that you Contact Apple Support so that they can assist you directly with this.

Thanks for using Apple Support Communities!
