Blogger posts have labels and a permalink that the Blogger editor controls. A draft sent from WritingTools arrives as the title and the body. Add labels in Blogger if your blog uses them for navigation. Check the permalink before the post is public, especially if the title is long. Changing the title later does not always change the URL Blogger already assigned.
The body is HTML. Lists, links, and headings from the WritingTools editor should come across as HTML, not as a screenshot. If a heading looks like a plain paragraph on the blog, the theme’s post template is not styling that tag. Fix the theme or adjust the heading in Blogger. Do not keep republishing from WritingTools hoping the theme will change.
Comments, pages as opposed to posts, and the blog’s layout gadgets are Blogger settings. This connection creates posts. If you need a Page in the WordPress sense, that is the WordPress connection’s Posts or Pages choice, not Blogger. One Google account can own several blogs. Pick the blog on purpose. The name of the connection should include the blog’s title so the editor menu is not a list of identical “Blogger” rows. If Google asks for access again after a password change, disconnect the connection and start the Google step over. The old grant does not update itself. Drafts already in Blogger stay there. Only new publishes from the editor need the new grant. If the account owns a blog you do not want to write to, do not select it just because it appears first. The editor will keep sending to the blog you saved until you edit the connection and choose another one. Blogger pages, as opposed to posts, are not created by this connection. A static about page still has to be edited in Blogger. Comments and the blog’s reading settings stay there too. Use the draft status when you want to add labels and check the theme before anyone with the blog’s address can see the post.
