Q: How do I resolve issues with UPayment not appearing or functioning with the new WooCommerce Checkout Block?

A: The UPayment feature is currently not natively supported by the new WooCommerce Checkout Block experience. You can resolve this issue immediately by reverting your checkout page to use the classic WooCommerce shortcode.

Please follow these steps:

Checkout Block Workaround
Go to your Admin Dashboard.
Navigate to Pages -> Checkout -> Edit.
In the right corner of the editor, look for the three dots (...). Click on them and select "Code editor."
You will see a code block similar to this:

<!-- wp:woocommerce/checkout --> <div class="wp-block-woocommerce-checkout alignwide wc-block-checkout is-loading"><!-- wp:woocommerce/checkout-fields-block -->

🚧
Important: Before making any changes, we highly recommend you copy this entire code and save it as a backup.

Replace the entire existing code block with this single line:

<!-- wp:shortcode -->[woocommerce_checkout]<!-- /wp:shortcode -->

Click "Save."
Refresh your checkout page to confirm that the UPayment option is now working correctly.

This action forces WooCommerce to use the traditional checkout structure, which is fully compatible with UPayment.

If you would prefer our support team to perform this configuration for you, please reach out to us, and we will help you with.
