Website banner language issue

Hello everyone ! I currently experience an issue with the language of our website banners. Despite having translations set in Localizable Information for titles in English, French, German and Italian, the banners aren't adapting to the user's chosen language. The title always displays in French, while subtitle ("Open in the app") remains in English, irrespective of the user's language preference. Would anyone know how can I make sure that our banners dynamically translate according to the user's language choice? Is there a setting somewhere in the apple product page that I'm missing? Thanks
