Hi, thanks for the screenshot. It shows clearly there IS no genre called News at all so there is nothing wrong there. Which means I cannot explain why the news sitemap would choose to show “News” as genre tag for some posts.
Can you send a screenshot from the edit page of https://noticias.gospelmais.com.br/malafaia-mostra-extrato-conta-revela-dinheiro-suspeito-87432.html for example? What is shown there in the Google News Genre field?
Also strange that your sitemap shows on /?feed=sitemap-news but not on /sitemap-news.xml while you are using pretty permalinks. Have you tried refreshing/resaving the Permalink settings?
Other remark: when adding Google News Keywords, try to use more general type of keywords as for example used in this list https://support.google.com/news/publisher/answer/116037 … Like “Politics” and not “Pastor Silas Malafaia”. Google News keywords are NOT the same as SEO/meta keywords. They do not have to be used in the text itself, they are to tell Google News about what category of news it is.
