On another computer, no problem! I can switch the language with the button on top of admin panel. I don’t have the the language switch button on my smartphone: I have a screenshot.But I can’t published it.
Even if I choose French on my computer, on my smartphone is blocked in English.
It doesn’t remain in French on my smartphone.
When I want saved the language in Settings > General, I choose french for “Langue du site” (website language), I save and en_US is always selected.. I can’t save in French on my Smartphone…
