import Loading is missing in the example at "Add a <Loading> component"

[juanmaguitar]

at Add a component the example should be like this

// File: /packages/my-first-theme/src/components/index.js

//
import Loading from "./loading"
 ...
<Main>
  <Switch>
    <Loading when={data.isFetching} />
    <List when={data.isArchive} />
    <Page when={data.isPage} />
    <Post when={data.isPost} />
    <Page when={data.isDestinations} />
  </Switch>
</Main>

// ...
