Expo + Storybook - Navigation links don't work on web

[chrisgeorge87]

Describe the bug
The Storybook page in the web browser isn't updating when you click different stories. It always shows the first (in my case, the Welcome story that is included by default). It does update on Expo in the connected iOS simulator. I'm using 5.2.0-beta.25 as with 5.1.x, the preview in the Navigator tab on iOS wouldn't update from selecting stories.

To Reproduce
Steps to reproduce the behaviour:

1. create an expo init project
2. follow steps from https://github.com/storybookjs/storybook/tree/next/app/react-native (export conditionally in App.js as the guide suggests)
3. run yarn storybook in one terminal tab and yarn ios in another (use iOS simulator from xcode)
4. try changing story in the web storybook - it does not update the story shown in the web page, only the one in the simulator

Expected behavior
The story shown should be the correct one in the web browser

Adding to the above, I've since found that the 'Welcome' page content it is showing all the time is from PreviewHelp.js from react-native-server, rather than the Welcome component and story that is created when you first add storybook to a project, just for added info.

Hi.

This is not a bug but intended behaviour, there is no content to show in the web (it is React Native app that you are playing around, not the web).

Closing the issue.
