Adblock doesn’t work beyond browser — It blocks ads in the browsers only, but not in other applications.
If you have your own WiFi router, you can block URLs from your router setup. Such setting may be called as URL filters. Here’s a short list of blocked URLs from my own router from where that ads are coming. The list is not comprehensive. I occasionally add suspicious URLs sources from which ads are coming.
It works well. And I don’t have 99% irritating ads on my connected devices.
