What I was trying to do:

I want to share a URL (and have the first page loaded) like any other social media

What I expected to happen:

being able to share an article from La Presse (ex : https://www.lapresse.ca/actualites/politique/2024-02-06/publicites-sur-facebook/la-caq-n-est-pas-solidaire-lance-le-pq.php?sharing=true)

What actually happened:

I cannot share anything

ALSO : I cannot copy the text somebody wrote in a post. A user wanted to copy his text and post the same text to another government. He was not able to do it from our website.
