TrueLayer uses its own template file for displaying the checkout page and should work with most themes. However, the plugin is only tested with the Storefront theme and use the Astra WordPress theme on the plugin demo site. We do not guarantee that it will work with other themes. Common situations when errors occur are:

• Themes or plugins with customized template files for the WooCommerce checkout page.
• Themes or plugins that modify the checkout into a multi-step checkout.

Krokedil and TrueLayer do not offer help with adapting your theme or plugin within regular support.
