To turn off SharePlay on your Apple TV, follow these steps:
- Open the Settings menu on your Apple TV.
- Go to 'Users and Accounts'.
- Select your username.
- Choose 'Shared with You' or 'Share with you'.
- Turn the setting off by toggling the switch.
To disable SharePlay on an iPhone or iPad, if you never (or almost never) want to use it:
- Open the Settings app.
- Tap on 'FaceTime'.
- Select 'SharePlay'.
- Toggle the switch to turn SharePlay off.
Keep in mind that SharePlay is initiated by a FaceTime call on an iPhone, iPad, or Mac, and if none of the Apple TV users are in a FaceTime call, SharePlay shouldn't interrupt your shows. To ignore a SharePlay invitation initiated by someone else, turn off 'Shared with You' or 'Share with you' on your Apple TV.
