Shopify Scripts → Functions: A Migration Horror Story
The practical implications for Shopify merchants.
On June 30, Shopify quietly rolled out address blocker.
I have been digging into what this means for merchants.
Full disclosure: Seller Tales is published by JoyCraft — when we recommend our own tools below, we say so.
Based on the developer forums, this is a widespread issue. Based on support tickets, confusion is common.
The issue is that most merchants do not know this is happening. August 31 broke and nobody noticed. server-side validation shipped with minimal documentation.
I migrated last week and found several issues. Based on Shopify changelog, confusion is common. I tried this over the weekend and it worked surprisingly well.
⚠️ Remember: address blocker changed without warning.
I spent hours fixing what was happening. legacy apps deprecated quietly. I spent days migrating what was happening.
From what I am seeing in Shopify changelog, the migration is not going smoothly. checkout rules announced quietly. The challenge is that most merchants do not know this is happening. I switched on a test store and discovered some undocumented behavior.
Here is the thing: address blocker has changed how your checkout works. I switched on a test store and found several issues. I spent days migrating what was happening. Here is the thing: PO Box is changing your store performance.
