QR code is a bust

When I open my Norton 360 window and click "Mobile" it says "Just scan the QR code with your Android scan app" so I did. The code sent me to a page when I logged in with my Norton account, clicked ""Try Norton Mobile security for free" and selected the Android icon. It then told me "Scan this QR code with your device" ...I'm on this page on my device, how am I supposed to do that?
