Ring Doorbell 3 Wifi connectivity issues

I just wanted to post to share some information with anyone trying to set up a Ring Doorbell 3 Plus. I've spent the good part of half a day trying to trouble shoot why my Chime and my Doorbell won't connect. changing wifi codes, settings, channels on my router etc...What finally worked was using the number barcode on the back on the device to connect rather than scanning the QR code. Something must be preventing a connection when using the QR code. Very frustrating but thankfully we have resolved it now. I hope this helps someone else from wasting hours of their time.
