Sure enough, sorry for the illustrations. I start again. In French, for example, I fill in the profile localization field, type the city and the API automatically proposes me, city + region + country. I save you.
But the city then disappears from the profile, it remains only region + countries (see fr.png)
I realized that if I just switch to the English language, the display is then correct, city + region + country. (See en.png).
If I switch back to French, the city is no longer displayed, only region + country.
You understand?
