WhatsApp Built in Scanner Won't Work
Found a decent workaround: I managed to scan the native app in Windows, installed from the link whatsapp.com/download. It's not a perfect solution, because I rather have it as a tab on my chrome, rather than a stand alone application, but it's close enough. I wish Whatsapp will come up with another authentication method, because it seems that many users are experiencing problems with the current approach.
