Hi Ross,

Please see this issue. If you export a class on the same line you will loose information in the react developer tools.

Advised not to do

export default class Named { }

Doing this in two parts resolves the lost information issue.

class Named { }
export default Named;

Same is applicable to

export default function Named() {}

export const Named = () => {}
