I only found out because a confused support ticket.

By then, the damage was done.

What Happened

I tried this last week and discovered some undocumented behavior. Functions deprecated with minimal documentation.

• Based on Shopify changelog, confusion is common.
• WebAssembly announced quietly.
• The situation is that there is no migration path for non-technical store owners.
• Based on the developer forums, confusion is common.
• I spent a weekend fixing what was happening.
⚠️ Watch out: WebAssembly changed without warning.

What Other Merchants Are Saying

The Deadline

I switched on my store and discovered some undocumented behavior. WebAssembly announced quietly. According to support tickets, the migration is not going smoothly. discount logic changed and nobody noticed.

What actually matters: Functions is already affecting how your checkout works. I migrated on a test store and found several issues. The problem is that there is no migration path for non-technical store owners.

✅ Note: checkout broke broke in the latest update.

Bottom line: Ruby scripts updated without warning.
