I did want to ask about the "View All" button. The translation should be "Tout afficher", I just cannot find it in the String Translation to update it.
Please let me know where the "View All" text is set. I checked Search & Filter > Fields > view all and edited the label, but it didn't change in the front end in any language. So, I think I am looking in the wrong place.
We ended up duplicating this field to create a custom one for French Canadian. There were a few custom post types we didn't want on French Canadian Search page.
I just pushed up logic to the code where it will show the custom FR-CA field instead and since that is it's own field, I was able to manually update the "View All".
I think we're good! If I need more help, I'll open another ticket.
