Thanks for your reply!
Please note that it is the same for automatic and non automatic content.
I checked the posts block settings, and tried different options about images, titles, authors, etc. Everything works fine but the images.
I can add images ?separately? from the library or my desktop. But if there is a feature image or an image in the content of a post, it does not appears in the newsletter post blocks.
As a reminder, it works for the domain.xyz. Not for fr.domain.xyz neither nl.domain.xyz.
