Ring Doorbell is updating for 12 hours.

I have just tried to install my new Ring Doorbell and it has been flashing the grey light on and off for 12 hours after about 10 minutes it flashes bright blue for a minute then back toflashing grey.I have reset the unit and tried again with the same results. I reset once more and checked on the app. It says the unit is online. I press the doorbell and it rings and nothing else. No notifications or any sign of the camers operating.What can I do to get this thing to work??RegardsWayne Burnside
