Since updating to iOS 26, I can no longer link my iPhone WhatsApp app to WhatsApp Desktop on Windows. Every attempt to scan the QR code results in an “Unexpected error” message on the desktop app.
This issue only occurs on iOS. When using an Android device with the same version of WhatsApp Desktop and same network, linking works perfectly.
I contacted WhatsApp Support, and they confirmed that the problem appears to be related to iOS networking or connectivity handling rather than their app.
Thanks for the post, this is very interesting and should be reported to Apple Support Communities as they'll be able to help.
But we appreciate your interest in participating in the forums! These forums are for questions about developing software and accessories for Apple platforms. Your question seems related to a consumer feature and is better suited for the Apple Support Communities

Hope gets resolved quickly.
