If a source does not interest you, you can delete it from your feed and in Preferences insert which topics you don't want to read
Does Google Now offer information that matters little or nothing? No problem, now you can customize the news, excluding those that come from publishers that do not interest the user. The news, reported by users on Reddit, confirms that by clicking on the menu at the top of the news, you can choose to communicate to the app that you are not interested in a specific source and therefore no longer follow it.
In addition, you can customize the content shown in the feed, and specify that you are not interested in news on certain topics (sports, fashion, cinema, and so on). The functions may not yet have appeared in the apps: Google has confirmed the release process to all in a short time.
