Hello,
Sorry I did prepare the screenshot but forgot to post them here.
The first one : https://prnt.sc/1uYx88bayadC
and then : https://prnt.sc/3qNgIzPfQh9X
The issue with the layout of the quantity on the mini-cart is resolved, it was caused by my CSS modifications on my child theme.
I renamed the translation file and it fixed the “shopping cart” translation, thank you.
Best regards
