cannot import default export

[Yeri Pratama]

So i have a module Flex.tsx

const Flex = (props) => (<div>...</div>)
export default Flex

Now i want to auto-import it by calling :TsuImport under cursor in other module, but nothing seems to happened after i run the command.

But when i use named export like this, the auto import works

export const Flex = (props) => (<div>...</div>)

Is this intentional, or is there any explanation for this?
