I've signed up for the free trial of Umbraco Heartcore. I'm following the information at https://umbraco.com/blog/introducing-graphql-for-heartcore/, which specifically says that the feature is available in the free trial.

I'm seeing two problems. First, a basic query that is copied from that article is returning:

{
  "data": {
    "content": null
  }
}

This is the query:

{
  content(url: "/home/") {
    name
  }
}

Here's the info for that piece of content:

It's published, the url is correct, the query matches the examples. But no data.

Second, that article as well as this document state that the schema documentation in the playground will be updated as new document types are added. That's not happening either.

I haven't found a way to get direct support from Umbraco for this question. I'm hoping someone here might be able to answer it or point me in the right direction.

Thanks.
