I received an email from Google complaining about this:

I have to say that I didn't add any new content/assets to my app since a while, I just made some fixes and improvements and now I'm getting this. Not sure what is this issue about. The took like half a month to review this versions.
They also mentioned this:
About the News policy Apps that select the ‘News’ category but exhibit content that does not meet these requirements are not permitted in the News category of the Play Store. News apps that require a user to purchase a membership must provide a content preview for users prior to purchase.
