Post purchase survey not rendering

Topic summary

Issue: A post-purchase survey (Checkout UI extension on the thank you/order status pages) isn’t rendering despite following Shopify’s tutorial. The goal also includes adding an app-powered button next to each product on the order details page in classic customer accounts.

Key guidance: Checkout UI extensions on thank you/order status pages are supported on all plans except Shopify Starter; Plus is not required. The extension renders only in the actual checkout flow (not in Shopify admin) and won’t show for orders paid with Shop Pay. Checking browser console logs for errors was recommended. Alternatives for adding buttons/functionality include custom template sections or using the AJAX API.

Follow-ups from OP: Believes code isn’t the issue (copied tutorial). Asked whether custom template sections can be added via an app and how to confirm if their store is on the Starter plan.

Additional suggestion: A no-code third-party option (Gojiberry Survey & Feedback) was proposed.

Status: Unresolved. Next steps hinge on verifying store plan, testing non–Shop Pay orders, reviewing console errors, and clarifying app-based template section feasibility.

Thank you for your reply Liam. I really copy-pasted the code from the tutorial so I really don’t think this is the reason.

If I am correct a custom template section can’t be added via an SHopify app correct ? I am new with Shopify so sorry if this is the case. I would like this button to be create via an app as I would like all the Shopify websites owner to be able to use the tool I am working on without having to code.

How do I know if I have the Shopify Starter plan ?
