What decides ad display language?

I have implemented admob ads in my react-native app.

My app supports three languages, Korean, Japanese and English.

Recently, I have realized that even though I am in Korea and my phone's device language is set to Korean, I see ads shown Japanese. 

As far as I know, a publisher cannot arbitrarily control in what language ads are shown and Admob decides that by itself.

In this case, could I know what factors are used for Admob to decide what language ads to show?

I have the same concern here. My app has only 3 supported languages: English, French, Spanish but we have seen ads popping up in German. 

This is affecting user experience as the ad is not relevant for the user. Could you please enlighten us why is this happening and how can we prevent this? 


Best regards,
Si Wei

You can select your site's primary language during the sign-up process. If it is approved, Google will serve relevant ads to your pages in the appropriate language, even if your site contains multiple supported languages.
