Ads are in foreign language

Hi, Jimbo1901.

Without knowing which specific application you're referring to, we're unable to offer a definitive answer. It may be that the app or apps you're using just use that particular language in advertisements.

If that's the case, you'd need to reach out to the application developer for further information: How to contact an app developer - Apple Support

"Contact the developer of an iOS, iPadOS, or watchOS app

1. Open the App Store on your iPhone, iPad, or iPod touch.
2. Search for the app, then tap it. If you can't find it, tap the account button  or your photo at the top of the screen, tap Purchased, tap "Not on this [device]," then tap the app.
3. The app's product page appears. Scroll to the Ratings & Reviews section, then tap App Support. If you don't see App Support, make sure that you're signed in with the correct Apple ID.

Cheers.
