WhatsApp has implemented a new security measure that blocks users from logging in if their devices run outdated versions of Android or iOS. This server-side update requires users to update their operating system to regain access. The change is aimed at enhancing security by ensuring that users operate on platforms that receive important security updates. Affected users will see a dedicated screen during login instructing them to update their OS. The specific versions of Android and iOS that trigger this restriction have not been disclosed. This measure is part of WhatsApp's broader strategy to protect user accounts from potential vulnerabilities associated with outdated software. The update does not require users to download a new version of WhatsApp to experience the login block. There is currently no workaround for affected users; updating the OS is mandatory to access the app again.
