shopify checkout extensibility blocks place order
A checkout UI extension that throws on Place order kills paid traffic at the last step. Disable the newest extension first, then pin versions during campaigns.
The actual problem
A checkout UI extension throws on Place order after a routine app update — paid traffic dies at the last step.
Do this
- Reproduce Place order on mobile for top payment methods.
- Disable the newest checkout extension until green.
- Pin app versions during paid campaigns.
- Add a post-deploy ‘Place order’ smoke check to release process.
