Has anything changed in the latest version of Woocommerce 4.20 with WordPress 5.4.2 The above code has stopped working. Please guide.

@KoolPal not that I am aware of. I just added it to a site and it worked for me.

@jessepearson Thanks. I realized that one of the plugins I used had changed the email ID slugs.

Now I am seeing some PHP warnings and notices when emails are sent. Can you please guide me? (This is with the debug.log ENABLED)

Thanks a lot!

@KoolPal that could be many, many things. If you're not seeing it once the snippet is disabled/removed, then you may need to reach out to a developer for help. You can also try the troubleshooting here: https://docs.woocommerce.com/document/woocommerce-self-service-guide/#section-4

Thanks @jessepearson I will explore with the plugin author whose email is showing these.

Thanks again
