Overview
- WhatsApp began rolling out the server-side login block on Tuesday, Oct. 6, 2026, and some users now see a non‑skippable screen that prevents the app from opening until a system update is applied.
- The change is enforced from WhatsApp’s servers so users can encounter the block without downloading a new version of the WhatsApp app from an app store.
- The on-screen message tells affected users how to check their phone’s iOS or Android version and instructs them to install the latest system update through the device settings before access is restored.
- WhatsApp has not disclosed which specific iOS or Android versions will be barred or the full scope and timing of the rollout, and reports say the feature is currently appearing for selected accounts.
- For people with older phones that no longer receive manufacturer or carrier updates, the rule could mean loss of WhatsApp access, while the company’s move aims to limit malware and account compromise that exploit unpatched operating systems.
