We have identified and fixed several critical bugs that were reported after AdGuard Browser Extension v4.2 for Chrome was deployed to 5% of our user base. These bugs were affecting the functionality of the extension.

To address these issues, we have released a hotfix. We will continue to monitor the situation closely. If no further critical bugs are reported, we will gradually increase the rollout to all users.

We apologize for any inconvenience this may have caused and appreciate your patience and understanding as we work to improve the extension.
