React fragment shorthand failing to compile

The project in question is using React-16.2.0 which has the capability to use Fragments and the Fragment shorthand.

https://reactjs.org/blog/2017/11/28/react-v16.2.0-fragment-support.html

While the full-length syntax works fine...

import React, { Fragment, Component } from 'react';

class TestingFragment extends Component {
    render() {
        return (
            <Fragment>
                <span>This is a fragment of text </span>
                <div>Another part of the fragment</div>
            </Fragment>
        )
    }
};

export default TestingFragment

The shorthand fails to compile and I am at a loss as to why this is. Fore example...

import React, { Component } from 'react';

class TestingFragment extends Component {
    render() {
        return (
            <>
                <span>This is a fragment of text </span>
                <div>Another part of the fragment</div>
            </>
        )
    }
};

export default TestingFragment

Which fails to compile as follows...

Failed to compile
./src/testingFragments.js
Syntax error: Unexpected token (6:4)

  4 |   render() {
  5 |       return (
> 6 |           <>
    |            ^
  7 |               <span>This is a fragment of text </span>
  8 |               <div>Another part of the fragment</div>
  9 |           </>
This error occurred during the build time and cannot be dismissed.

Is there something here I am missing about the Fragment shorthand syntax?

I think this is a reason:

https://reactjs.org/blog/2017/11/28/react-v16.2.0-fragment-support.html#support-for-fragment-syntax

screenshot

create-react-apps currently use Babel 6.26.0 for full support React.Fragment is needed Babel v7.0.0-beta.31 and above

======================= EDIT

It's working now with create-react-app v2 https://reactjs.org/blog/2018/10/01/create-react-app-v2.html
