Hello,
First of all, thank you for your purchase.
1. For the first source you linked, I searched but did not find an RSS feed for it, so the plugin will not be able to get content from this site. Instead, I can also recommend the Crawlomatic plugin I created, it can be used to scrape sites without RSS feeds. Please check it here: https://1.envato.market/crawlomatic
2. For the second URL, please use this RSS feed address to get content from this site: http://www.seg-social.pt/noticias/-/asset_publisher/9N8j/rss?p_p_cacheability=cacheLevelFull
