Why You Can’t Activate the Checkout Extension Block?

If you’re unable to activate or add a Checkout Extension Block, this is due to a current limitation set by Shopify.

At the moment, adding app blocks directly to the checkout page is only available for stores on the Shopify Plus plan. Shopify restricts checkout customization for non-Plus plans, which means merchants on other plans cannot install or manage Checkout Extension Blocks from the checkout editor.

What This Means for Non-Shopify Plus Stores

If your store is not on Shopify Plus, there’s no need to worry—this limitation does not prevent the app from working.

You do not need to add the block manually from the checkout page. Instead, you can simply:

• Open the app

• Configure the rules and settings you want

• Save your changes

Once set up, the app will automatically apply those rules during checkout, even without the Checkout Extension Block being added in the checkout editor.

Summary

• Checkout Extension Blocks can only be added on Shopify Plus stores

• This is a Shopify platform limitation, not an app issue

• Non-Plus merchants can still use the app by configuring rules directly within the app

• The app will function on the checkout page based on those rules
