go through your play store or the cloud or whatever Apple uses and see which of your most recent apps updated. odds are it’ll be either one you recently updated or one that you downloaded.

Android, Apple or what? There are apps that deliver news and killing them all can be like killing roaches. I’d delete or disable any app with “News” in the description.
