Change Spanish speaking commercials on Peacock

Greetings @user_qawo71! I'd recommend logging into your Peacock, going to your Account Settings, and ensuring your primary language is set to English. Also, if you are streaming using a Xfinity cable box, you can clear the box's cache for third-party apps by pressing the Xfinity button on your remote, navigating to the gear icon, and selecting Settings. From there, choose Privacy, go to Locally stored data, and press OK to confirm the clear. Finally, just launch the Peacock app again and log back in.
Please keep in mind that clearing your cache will sign you out of your apps, so be sure you have your sign-in credentials handy before trying this step.
Let me know if that helps.
