You can access a basic hosted store by visiting [your-company].booqable.shop if you enable the Booqable online store in your Online store settings.
If you want to use a store you have created in the new website builder, you will need to Publish your website from the theme editor.
Now, when you visit [your-company].booqable.shop, you will see your new website instead of the basic one.
Note: This doesn't affect components embedded on a third-party website.
To switch back, you will need to unpublish your new online store. You can do this by clicking Revert latest publication in your Online store settings. If you have published more than one update, you will need to keep clicking this option until the option is no longer available.
