I’m apparently not doing it right. I added tjkelly’s final code snippet (minus the third “delete_user_meta” line, because I don’t have any custom post types code) to functions.php, saved the change, and then tried both Edit Post and Add Post. The custom fields group is still at the bottom (below the post content area where Gutenberg blocks go). I’m using WP 5.3.2 with Meks’ Voice theme, if that matters. I put the new code at the very bottom of functions.php, right before ?>.
