There’s a filter for this. Specifically – generateblocks_container_tagname. I raised a bug ticket as there might be a bug regarding it and the tag name for the Query Loop Block.
I forgot to mention that I am using this page on my frontpage. That’s why I need to change the article element to something like section or div.
I already added content-page.php to my child theme and created a condition that if the page is in the frontpage it will change to section else use article.
Yes, though I have temporary fix on the first issue which is the options for the article element tag. I still wanted that you integrate it on the next update. This is very important for SEO.
