Checkout UI Extensions did not show up in checkout customize page

[TuanDangA]

Hi everyone, I've created a custom app with Remix template, created a checkout UI extension, run npm run dev to preview on my Dev store and it worked perfectly, but when I deployed the extensions to the app and installed the app to my dev store(set at preview checkout extensibility), the extensions didn't show up in the checkout customize page. Can anyone help out here? any applies is appreciated

Hi Everyone,

I'm facing the same issue with Shopify app version 3.48.0 and 3.48.1, I could not see my extensions in Checkout Editor on my development store and testing store (Shopify Plus plan). 

I tried with the example from Shopify https://github.com/Shopify/example-checkout--custom-banner--react but still not see the extension in this app on Checkout Editor page 

Thanks,

Hi @TuanDangA 

I have solved this problem by the following steps:

1. Deploy app to Shopify Partner App

2. Create release version on Shopify Partner

3. Deploy app again with this option

4. release this version

Then you can see extension in Checkout Editor page.

Hope these steps can solve your issue as well.

Thanks, I have spoken to Shopify Help Center. It seems that right now we can't test checkout ui extensions in the dev store, we can only preview it, but even if we install the app into the dev store, the extensions won't appear. We have to install the extensions to a Shopify plus store to be able to see the extensions

Hey, I had your problem but I managed to solve it, check here:https://community.shopify.com/c/extensions/simplified-deployment-not-updating-extension/m-p/2166941/...

The trick was to uninstall the app, set the preview off and then reinstall the app. I think it's a bug in the simplified deployment.
