Disclaimer AdGuard for Android is not an open-source project. We use Github as an open bug tracker for users to see what developers are working on.
This quick update fixes a bug that could have happened to our long-term users. If you have been using AdGuard for a few years and your security certificate expired, it could have lead to an HTTPS filtering failure. After this update, you will see a notification on the app’s main screen. Tap on it and follow on-screen instructions to reinstall the certificate and resume HTTPS filtering.
