1. This shortcode works perfectly, thank you!
2.Yes, Under WP Show Posts -> Selected List -> More Settings I have entered “3595” in the Exclude Post IDs field. For an example if where this shouldn’t be displaying, if you go to this post (https://afterschoolfinance.com/live-below-your-means/), the first post at the bottom where WP Show Posts displays is Christmas on a Budget. This is post 3595, which I have tried to exclude because it is seasonal.
