ios/swift/touchID/error: there is not an associated public key for specified client_id/user_id/device

My team is considering Auth0 to prototype initially with iOS using TouchID.
If I can demo this functionality successfully, we have lots of other platforms we could extend Auth0 onto.

I’ve successfully implemented the v1 TouchID example, and can initially register and then login.
But I haven’t been able to duplicate that initial success.
I’ve deleted the user I created, the client, etc…
Regardless as soon as I authenticate with TouchID I get the error:

there is not an associated public key for specified client_id/user_id/device

It appears that Auth0 is storing the TouchID token separately from the user or client since it doesn’t seem to get deleted when I authenticate.

Is there a trick that I’m not seeing on how to make this work?
I’ve been looking through the dashboard but can’t identify another repo for the TouchID tokens…

Any help would be appreciated.
