Ring app doesn't see lock in Amazon Key

I have a Schlage Encode lock added to my Amazon Key account. However, during my adding a lock in the Ring app, when it gets to the point of connecting to Amazon Key, a very brief screen pops in stating there is no lock in my Amazon Key account and provides a button to bring up the Amazon Key app. When the Amazon Key app appears, it clearly shows a lock in the account. I have deleted/re-added accounts, deleted/re-added lock. deleted/re-added apps, and gone through the set up process multiple times with the same problem. I am running Android 8.0 a Samsung J3 phone.

Who should I contact to help me with this?
