Cant complete setup "Hmm, something went wrong"

Ring Video Doorbell 2 Model 5UM5E5 The worst setup experience of my life! This ought to be a total doddle, and it isn't. 1. Creating the Ring account and logging on required many attempts with many demands for verification codes, and many demands that I verify my email address. Got past this eventually (how?). 2. Now to set up my Video doorbell 2... "Add a Ring product" "Doorbells" "Scan the code" - it wont scan, so I press "SETUP WITHOUT SCANNING" "Ring video doorbell 2" Where to set it up...my address, OK. Give it a name "Front Door" No removable battery Press the orange button. Spinning white light on the front of the doorbell. "Hmm, something went wrong" "Please start the setup process again." Go back to step 2. above. Repeat this process for ever...? The device is stuck in setup mode with the spinning white light. I have spent 2 hours on this so far. How much longer?
