I installed this language module : https://github.com/Imaginaerum/magento2-language-fr-fr
Now, due to the Magento translation loading order :
- Loading the module translations
- Load theme translation file
- Load translation package info
- Load db tranlation. (Inline translation)
app/design/frontend/COMPANY/PROJECT/i18n/fr_FR.csv file is not working (not prioritary).
I tried creating a new translation package, but it's not working neither...
