Hi everyone! Hope you are doing well
After switching Customer Accounts from Legacy → New, the Checkout → Customize page in Shopify Admin no longer loads.
What I’ve confirmed/tried:
-
checkout.liquidis fully removed -
Toggled Customer Accounts back to Legacy → New
-
Logged in via Incognito / cleared cache
-
Disabled all checkout-related apps
The storefront and checkout work fine outside admin — the issue seems limited to the admin checkout preview after migrating to New Customer Accounts.
Has anyone encountered this before?
Did it require a Shopify support reset, or is there a known workaround?
Thanks!
