I know for a fact it does. I can view the logs in AdGuard Plus, the only time I see an ad in Words With Friends or Flipboard on my iPad is when I'm off my Tailscale VPN (which goes through AGP). Apps that serve their ads directly, like YouTube, are not blocked sadly. But there are multiple workaround apps for that on Android atleast. Also some apps don't work with the tracking blocked, like Fox Sports, but I just whitelist the minimum amount needed on a per device basis.
