Microsoft Edge for Android now has Adblock Plus built in, stopping intrusive advertisements and trackers from spoiling your browsing. Ad blocking is now available to beta users, and will be rolled out globally very soon.
Once you have the update, you can activate the ad blocker in Edge's settings. The Edge beta program is currently full, but once spaces reopen you'll be able to opt in via the Google Play Store.
