Can't identify my Doorbell2's S/N for Recall

[https://support.ring.com/hc/en-us/articles/360050949611](https://support.ring.com/hc/en-us/articles/360050949611) The above link was pointed out in another post that you can enter your S/N to see if it's impacted. However, I'm getting the error message after entering the S/N: Results: Invalid DSN | Character Count Other than selling consumers made-in-China garbages, can Ring also take responsibility and fix the mess Ring created, please?
