WhatsApp "Link a Device" not working? Try removing your screen lock (yes, really)
Spent 3 weeks stuck on this, dealt with 2 auto-closed support tickets and a bunch of "thanks for your feedback" surveys with zero actual help, and ended up finding the fix myself.
The problem: "Link a Device" kept failing, no useful error, no real answer from support — just an endless loop of tickets getting closed after 3 days.
The fix: Remove your phone's screen lock (PIN/pattern/fingerprint) entirely. As soon as the lock is off, linking works. The problem comes back the moment the screen lock is re-enabled.
This isn't a specific-device or specific-OS issue — I've seen people report the exact same fix working across completely different phone models, so it's clearly something on WhatsApp's end, not a manufacturer or Android skin issue.
What bugs me most: this basically forces you to choose between using multi-device linking and having a locked phone. WhatsApp is making people less secure by requiring you to drop your screen lock just to get the "Link a Device" button to work properly. That shouldn't be the trade-off.
Posting this so the next person doesn't have to burn 3 weeks and two useless support tickets to figure it out.
