I have an RN Amplify project setup and working, the default for the Amplify config is "aws_appsync_authenticationType": "API_KEY",. This is “public” mode. The app also supports Cognito user pool for users who want to create an account. Right now what I do is call Amplify.configure() like so to switch to userPool when a user creates an account:

  Amplify.configure({
    API: {
      GraphQL: {
        endpoint: amplifyconfig.aws_appsync_graphqlEndpoint,
        region: amplifyconfig.aws_appsync_region,
        defaultAuthMode: 'userPool',
        apiKey: amplifyconfig.aws_appsync_apiKey
      }
    }
  })

This works, however, when the user signs out or deletes their account and I call Amplify.configure() and change the defaultAuthMode back to apiKey, I get generic ‘identity’ errors calling the API.

Is there a better way to do this or an “official” way to support public vs. private users? I need to support both and obviously support sign out / delete account. The Amplify docs say that you can use an Unauth Cognito role created by the project in place of the API_TOKEN but I could not get that working. TIA.
