WooCommerce checkout/order-received

Successfully displaying an ANB at the WooCommerce ‘checkout’ page. The ANB is alerting the user to add certain information in Order Notes if desired.

However, the ANB also displays on page ‘checkout/order-received’ which is a page generated by WooCommerce and has the same page ID as ‘checkout’. The message is now out of context and not wanted.

Is there anyway to prevent display of the ANB if ‘order-received’ is part of the URL?

Thank you.
