Add App Block Doesn’t Work

If you're unable to add an app block while customizing your product template, this guide will walk you through the proper steps using the Build A Gangsheet App interface. It includes important tips on selecting the correct app blocks based on your gang sheet variant.

1. Open Theme Editor for the Correct Product

Navigate to the Shopify theme editor directly at:

https://admin.shopify.com/store/build-a-gang-sheet/themes/175105802520/editor?previewPath=%2Fproducts%2Fupload-by-size

2. Access Your Sales Channels

In the left-hand panel, click Sales Channels, then select Online Store.

From here, click Customize next to your current theme.

3. Locate the Product Template

From the top menu in the editor, select the product template you’re working with. For example, click Standard Gang Sheet if you're customizing that variant.

Hover over existing blocks to determine where you'd like to insert your app block.

4. Add the Appropriate App Block

In the left sidebar, go to the Apps section within the block editor.

Select the app block that suits your gang sheet variant:

  • Gang Size → Use with Upload By Size
  • Gang Upload → Use with Upload A Gang Sheet
  • Gang Sheet → Use with Gang Sheet and Rolling Gang Sheet

5. Save Your Changes

After selecting and placing the appropriate app block, make sure to click Save in the theme editor. Failing to save will prevent your changes from appearing live on your storefront.

Why This Fix Matters

  • Ensures your product templates are correctly tied to the app blocks from the Build A Gangsheet App.
  • Prevents rendering issues where app functionalities fail to display for customers.
  • Improves the consistency and reliability of the user experience on your storefront.
