Primary language and default versione

I set Primary language = FRENCH (LibraryThing.fr)
This parameter seems having no effect
When I launch manually Librarything it does not switch in french and when I launch from Librarything button in Tinycat, I see the english version

Perhaps I have not understood how use this parameter or is there a bug?

Thanks in advance

Are you logging into fr.librarything.com or www.librarything.com?
Because setting the language doesn't change the site. You have to change which site you log into.

>2 gilroy: Yes, but you actually want https://www.librarything.fr/ rather than https://fr.librarything.com/

Is Tinycat available in French at all?

>3 kristilabrie: I keep forgetting they changed that. :)

>4 MarthaJeanne: No. If you have a non-English TinyCat account your book data should still show up in the language you've saved it in, but the TinyCat-specific interface will be in English. (Localization of TinyCat is high on our list, though.)
