App block form theme app extension not appearing in the theme editor

[mkamalkayani]

Hi,

I have followed the theme app extension getting started guide and everything works fine except the app is not appearing in the Apps in the Add Section popup of theme editor. Any suggestions, how to debug?

Thank you

@JoshHighland I figured it out. The app block was registered for only a specific template( I think it was only product template) that's why it was not appearing in the home page.

You can find out on which template the app block will appear by looking at the template field in the app block section schema.

I had the same problem, keep calm and follow these simple steps :

1. Go to partners.shopify.com

2. Tab 'Applications'

3. Select your application

4. Go to 'Extensions'

5. Then select your extension

6. And enable the option to preview in development store

Enjoy!

That helped me a lot, although the partner UI has changed a bit. Meanwhile, these are the steps you need to follow:

1. Go to https://partners.shopify.com.
2. Navigate to `Apps`.
3. Select your application.
4. Navigate to `Extensions`.
5. Find the card that says 'Development store preview' on the top.
6. Find the button 'Turn on' in the upper right corner and click it.

Thank you! turning on for dev stores was the trick.

I actually have enabled the theme extensions as you recommend but once I go to theme editor I still see a 404(the app of course is installed in development store as well as the extensions)
