Our recommendation
- Update Chrome on all Android devices via Google Play to 156.0.8078.47 or later, preferably the latest Stable build.
- Verify the installed version at chrome://version on managed devices and enforce automatic updates.
- Include staff-owned devices (BYOD) that access company data.
