Can I change my Shopify connection after it is installed?
The Shopify Integration App does not allow you to change the Shopify and/or NetSuite connection once it's installed. The reason is that we are registering order and product webhooks in your store at the time of installation. If you change it, your integration will become corrupted.
The ideal solution would be to install another copy of the integration in order to switch the Shopify connection.
