Broken tutorials in "Build your first AWS Amplify and React App"

User is following https://amplify.aws/learn/courses/Fullstack-for-Frontend-Developers-e7319 and found a couple of errors / items that need clarification:

Lesson 9

<NoteUICollection overrideItems={({ item, idx }) => {
  return {
    overrides: {
      Vector31472464: {
        as: 'button',
        onClick: () => {
          setShowUpdateModal(true)
          setUpdateNote(item)
        }
      }
    }
  }
}}
/>

There is no explanation of how we get the Vector31472464 label; when they were going through the course, they had to find it in NoteUI.jsx, while the course implies it will be in NoteUICollection.
This snippet should not have as: 'button', as this behavior hides the edit button
The "edit" button brings up a blank CreateNote modal, and does not fill from the existing text.

import { DataStore } from 'aws-amplify'

This line generates an error ERROR in ./src/App.js 28:18-33 export 'DataStore' (imported as 'DataStore') was not found in 'aws-amplify'. They fixed this to read from '@aws-amplify/datastore, which fixed the compile error.

Lesson 12

References to AmplifyProvider need to be converted to ThemeProvider

Lesson 13

They believe the sequence to connect the backend to the hosted frontend has changed since publication of the tutorial; clicking through the frontend connection doesn't require a backend connection. Even so, after going through View App Settings -> Edit and creating a service role, they were unsuccessful in connecting the backend. The frontend hosting and auth appears to work, but it doesn't load any notes from test data, nor save notes that you create.
