Adguard has been blocking sites after iOS 14.4 update

AdGuard is an app. If you didn’t download it you don’t have AdGuard on your phone. But to check open Search (put your finger on the middle of the screen and swipe down) and enter “adguard” in the search field. Does it appear? There is no built in ad blocker in iOS 14, so if something is blocking ads it is an app that is installed on your phone.

You can also go to Settings/Safari and tap on Content Blockers. Do you see any listed?

To customize AdGuard open the AdGuard app, tap on the Settings gear/Safari Protection/AllowList.
