    Issue Description: The App can be loaded successfully to the web browser. But the app fails to link to the host page.
    There is an error message display at the Browser Developer tool.

    The Error message is as follows:
    Access to XMLHttpRequest at ‘https://www.bookuai.com/wp-json/wplms/v1/track/?client_id=rIvWAlWFKvYrm6qnUsl1jUJ&access=0’ from origin ‘http://localhost:8100’ has been blocked by CORS policy: No ‘Access-Control-Allow-Origin’ header is present on the requested resource.

    *https://www.bookuai.com/ is the host webpage url

    The CORS are most likely returned in response. If you’re using caching plugin w3tc then make sure it is not adding any .htaccess code to remove cors.
    On many sites using w3tc we found this issue.
    I will need admin credentials to further debug this.

    Hi,

    The issue is caused by third-party plugin.

    Your app already working please deactivate plugin: WooCommerce Blocks. Then try to run your app.

    Refer this image of working app from your site:http://prntscr.com/qhhcqw

    Same thing you have to do for your local setup.

    For build update your config.xml like this http://prntscr.com/qhsegc

    code:   <access origin=”*” />
