Existing wired Ring doorbell without a QR code or 5 digit PIN code

I moved into a new home and it had an existing Ring doorbell. I went thru the Ring process to get the prior owner to release the doorbell to me. The QR code does not work and there is no PIN code on the battery or inside the battery cover. So far I have not been able to set up the doorbell. I tried pushing the set up button inside the cover and the front was spinning white but it would not go any further in the process. Any ideas?
