Back button navigation doesn't work

[pkese]

... Click on site to navigate to login / members area,
then click browser back button:

location changes but page won't update.

solution is to wrap exported App in App.js into withRouter

import { withRouter } from 'react-router'

@withRouter // <-- here
@inject('store', 'routing')
@observer
export default class App extends Component {
   ...
}
