I have an iPhone 4S with WhatsApp.
I install WhatsApp Web on my PC. It starts, and displays a QR code. I'm supposed to use my iPhone's WhatsApp to scan the Qr code. The menu item to do this is supposed to be in "settings". When I open "settings" I don't see the option. It's supposed to be below "tell a friend".
What do I need to do to get the option to appear?
The option should be appearing in the iPhone software "WhatsApp"; it is missing from that software as installed on my device.
