Since iOS 14, for some users, our app is not localized anymore

Hello,
For some rare users, our app is only available in English, no matter what settings they used for their language (general settings and app settings).
It seems to be for some random users, and we cannot reproduce it.
We never had this issue before (the app is localized in 12 languages)
We would love to have a clue or advice on this!
Thanks
Hello! To be able to effectively analyze this problem, we’ll need to know what the Language & Region settings are for your users who encounter this problem. Can you ask them for that information, e.g. a screenshot of Settings > General > Language & Region (iOS) or System Preferences > Language & Region (macOS)?
