That said, is there a way to configure the emails as a template override like in WooCommerce?
I don’t get when the /templates/emails/ stuff get used – it still takes from the settings even though I try to override it my theme in /motopress/appointment/emails
Thanks for contacting us. I’ve replicated the same behavior and forwarded this case to our developers. Meanwhile, you may try to add the tags without using quotes (HTML might work without quotes).
