For discussing the development and usage of Checkout UI extensions, post-purchase extensions, web pixels, Customer Accounts UI extensions, and POS UI extensions
I have created the app and checkout UI extension using Shopify CLI. It makes a custom text field under the contact information. I have verified it works on a development store created from my partner account. The extension is versioned and deployed. I set up distribution as a single link for the Shopify Plus merchant and installed it on that Shopify Plus store. After installing the app, add the extension app through the app builder. After saving, it did not reflect in the store checkout but previewed in the app builder while adding.
Can anyone help out here?
