QR code is not loading I tried to connect Whatsapp on chrome. But when I go to https://web.whatsapp.com, QR code doesn't load. Rather it shows a continuously moving circle.

What might be the reason for this?
Make sure that you use the QR reader build in Whatsapp and not an separated app.
You can access the QR reader in Whatsapp by entering the menu at the main screen.
If Whatsapp Web doesn't show up in the menu list then you either haven't installed the latest version of Whatsapp or you have to reboot your device in order to make it appear in the menu.
