Not sure if it is even possible, but...
I started using the built-in Windows 10 news app. Much to my horror, I started seeing ads for "one weird trick", "foods to avoid", "you won't believe" and similar. (I have already placed Outbrain, Taboola and Zergnet on my blacklist, but that's a separate discussion).
Obviously, the News app is not Edge. Is it possible to extend ABP to News (and other Win10 apps)?
