POS Support After Legacy Extension Deprecation
The Shopify POS integration allows you to edit customer fields directly within the Shopify POS app for iOS and Android.
Note: In order to use the app on the iPad, the iPad must log in to the app at least one time. This is due to security measures on the iPad. If the iPad does not visit the app, it will not be able to display the fields in POS.
