Hi Samuele,
Elementor Loops with default configuration (using current query) may actually work if combined with the Posts/Product widgets or the archive widgets if used on archive pages. A more generic support will be added in the next release.
Other elements may only work if used on Archive pages – where they use the currently active query. Unfortunately there is just too many widgets out there and they change very often, for now we can only keep up with Elementor.
