Camera not scanning QR code

I have seen a few posts on this but no answers still. just got my system and trying to set up the camera. all it keeps saying is "ready to install follow instructions on app" the QR code is showing but the camera wont scan. ive tried restarting, deleting the app, unplugging the camera, everything. and still nothing. ive been on hold for almost 2 hours total for customer service. once they answered and then disconnected me immediately. now im back on hold again.
How do we get the camera to scan the QR code and have it stop saying "youre camera is ready to install:"
