In a Drupal 8/9 site, I can select the User's preferred language.
In the "Manage form display" page (for user's fields), there are two rows which are about language:
Language settings(settings = --no settings available--)
Language code(settings = "language select" as the only option)
Question 1 : What do these two options produce?
In the "Manage display" page, I can display only one item about the language :
As a result, if I visit my user profile page, I can see:
Language code: French
But if I change my preferred language in my user edit profile page into Dutch, there is no effect in my "User view" page: it is always "French"
ok, I can preprocess something and adapt the twig template to display my preferred language but this is not the answer I would like to have.
Question 2: I would like to understand this behavior because, as always in Drupal, I am sure there is a good reason for that.
