Google’s Manifest V3 platform is now active for Chrome extensions. GoGuardian is redesigning its extensions to fully support Manifest V3. Until that work is complete, organizations deploying GoGuardian extensions must enable a Manifest V2 extension availability enterprise policy to prevent disruptions.
Update Google Chrome to the latest version on your devices before enabling Manifest V2 support.
Google has identified unexpected behavior on Chrome version 123 that disables self-hosted extensions (including GoGuardian) when a user’s managed Google account is signed into a non-managed or personal Windows or Mac device. Update to Chrome version 124 or roll back to version 122 to resolve this. See Google Chrome issue 331061788 for details.
