WhatsApp Blocks Logins on Android and iOS Devices Running Outdated Operating Systems
WhatsApp has started blocking logins on Android and iOS devices that run an outdated operating system. The check is a server-side change, so it works regardless of the installed WhatsApp version, and it is rolling out to specific accounts on both platforms. Affected users see a new screen asking them to update the device software before they can continue.
The screen cannot be skipped. Until the operating system is updated, WhatsApp does not let the account log in on that device. Because the check runs on WhatsApp's servers, installing a newer WhatsApp build alone does not clear the screen.
