I've done a responsive website with default / 1024 / 800 / 320. (under the latest WWB 16 update).
Works perfectly on internet whatever the browser.
BUT in the preview, the French version does not follow the various displays (I get 800 size for the default and 1024 definitions and 320 for 320.
The English version (made by duplication of the pages of the French version) behaves normally in the preview.
This happens in Chrome and not in Edge.
I have erased the Chrome history and it still does the same.
I did erase C:/Users/fkerb/AppData/Local/Temp/preview/index.html just in case. Still identical issue.
Do you have a solution? (probably simple but obviously beyond my knowledge

Thanks in advance.
