I've been trying to work with Gutenberg all day and it's a bust. I use Word to write my posts then copy and paste onto my wordpress blog Gutenberg won't allow me to do any of that because If I do get it to paste into a paragraph block it never shows up when I preview it. Also Pexels does not work in Gutenberg so it is useless to me I'm staying with the classic editor until someone can figure out what is going wrong.
