@joostvandevijver thanks for the response.
I have taken the following steps but still see the issue.
– 1.5.1 of the plugin installed
– Removed all other plugins other than Woocommerce
– Removed all functions in functions.php
– Removed all custom Woocommerce templates
– Switched to theme twentytwentyone
Running Woocommerce 5.6 / WordPress 5.8
Any other ideas?
