10 SOLUTION Okay, first of all - you have to scan the QR-Code with the scanner that is built in WhatsApp . Not with some 3rd-party scanner -app. Click on " Whatsapp Web ", then the scanner opens immediately. BUT - apparently there is a problem with devices that have a display smaller than 4 inches! The scanner does not work, whatsapp scanner refuses to read the QR. It does nothing.I've tried 3 different phones and it does't work in any of them [SOLUTION] I solved it by switching off the "Dark Mode" in the browser, looks like "Dark Mode" the QR's white is not really white, and because of that the scanner doesn't pick it up. My WhatsApp QR scanner is not working when needed for WhatsApp Web . It seems blurry, while my phone's camera is actually perfectly clear. Secondly, I have restarted the phone none worked, same issu... So maybe a fix for some of you. I uninstalled whatsapp and downloaded whatsapp business app and got the code to verify phone number then uninstalled whatsapp business and went back to whatsapp and reinstalled it and got the code and all working. I got the code through sms. This was on android so not tested with iPhone. Hope this is a fix for you all.
